Here is the transcription of the images into a structured markdown format: ### Image 1 The image shows the word "IUPAC" in large, bold, yellow letters. There are Erlenmeyer flasks, and the liquids/vapors inside give off a teal and orange color. Below the flask is a 3D model of what appears to be the result of chemical reaction, and social media handles: "@iitjeeneetnotess" on Telegram and "@ittjeeneetnotes" on Instagram ### Image 2 # IUPAC Nomenclature @iitjeeneetnotess - Introduction (2° Prefix + 1° prefix + wordroot + 1° Suffix + 2° Suffix) - Nomenclature of saturated compound - Unsaturated compound - Cyclic - Bicyclo - Spiro - Mongfunctional group - Polyfunctional group - Ether - Benzene derivative ## IUPAC | 2 | 1 | 0 | 1 | 2 | | --- | --- | --- | --- | --- | | 2° prefix/ secondary Prefix | 1° prefix/primary prefix | wordroot | 1° Suffix/primary Suffix | 2° Suffix/secondary Suffix | | Prefix Suffix | | | | | $P + W + S$ - 2° Prefix. Tells us about side chain/branching/substituent in an organic compound - -X (halo) - -NO₂ (nitro) - -F (Fluro) - -Cl (Chloro) - -N=O (nitroso) - -Br (Bromo) - -I (Iodo) - -O-N=O (nitrile) ### Image 3 @iitjeeneetnotess - -R (alkyl) 1. -CH3 methyl 2. -CH2 CH3 ethyl 3. -CH2 CH2 CH3 propyl ${CH_3CHCH_3 \choose |} isopropyl \; \substack {--> \\ CH_3}$ 4. -CH2CH2CH2 CH3 butyl (n-butyl) $\substack{CH_3CHCH_2CH_3 \choose |} Secondary \; butyl $ or sec butyl $CH_3-CH-CH_2- \substack{ \choose | \\CH_3} isobutyl$ ${CH_3 \choose |} CH_3-C- Tertiary \substack{ \choose | \\CH_3} butyl$ Tert butyl $CH_2-CH_2-CH_2-CH_2-CH_3 \; n-pentyl$ $\substack{CH_3-CH_2-CH_2--CH-CH_3 \choose |} Sec \; pentyl$ $\substack{CH_3-CH_2-CH-CH_2-CH_3 \choose |}$ $CH_3-CH-CH_2-CH_2-Ch_3 iso \; pentyl$ ### Image 4 @iitjeeneetnotess $\substack{CH_3 \choose |} CH_3-C-CH_2 neopentyl \substack{ \choose | \\CH_3}$ Phenyl $CH_2=CH Vinyl$ $CH_2=CH-CH_2 Allyl$ $CH=C Ethynyl$ - 1° Prefix Tells us about whether compound is closed chain or ring The image contains line drawing of organic chemistry structures, including cyclobutane, cyclohexane, and bicyclo compounds. Describes: - Bicyclo - Bicyclo- Two cycles are fused into one another having more than one common carbon. - Spiro- Two cycle are fused Into one another having one common carbon ### Image 5 @iitjeeneetnotess - word root | No. of Carbon | wordroot | | --- | --- | | 1 | meth | | 2 | eth | | 3 | prop | | 4 | but | | 5 | pent | | 6 | hex | | 7 | hep | | 8 | oct | | 9 | non | | 10 | dec | - 1° Suffix Tells us about the Saturation / unsaturation in the comp Single band- ane ($=$ or $\equiv$ bond) double bond ene / two double bond - diene triple bond- Yne / two triple bond - diyne. $== ené \; yne$ $ex \; enyne$ - Two vowels can't come together. or one vowel and one y can't come together. then former vowel is cancelled $$->=->enediyne$$ $$\equiv -> \equiv ->dienkyne\begin{Bmatrix} dienyne \end{Bmatrix}$$ ### Image 6 - 2° Suffix Tells us about functionpal group in compound will be discussed later on - Nomenclature of saturated compounds. - only 3 Steps- 1. Selection of parent chain 2. Numbering of Parent chain 3. Naming of compound Selection of Pc Rule 1- Carbon chain having maximum no. of carbon will be taken as parent chain Image contains illustrative organic chemistry structures to illustrate rule 1 ### Image 7 Rule 2 - when more than one parent chain is present then select that carbon chain which has more no. of substituen Image contains illustrative organic chemistry structures to illustrate rule 2 - Numbering OF PC Rule 1 - numbering is done in such a way that Substituent gets lowest locant number Image contains illustrative organic chemistry structures to illustrate rule 1 Rule 2 - In case of more than One Substituent then follow first point Principle Image contains organic chemistry diagrams with numbers. (3,3,6) X (2,5) valid (2,3,6) (2,5,6) ### Image 8 Rule 3 - If first point difference rule fails, then numbering is done alphabatically. Image contains illustrative organic chemistry structures to illustrate rule 3 Naming of Compound: 1. locant no. of Substituent must be before name of substituent 2. Hyphen is Used to separate -> Number & letter 3. Comma is used to separate -> Number & Number 4. No gap between letter & letter 5. -methyl 2,2-dimethylpentane Rule-3 - always follows alphabatical order in naming of substituents Image contains a diagram and then names the structure. 3-ethly-methyl pentane Rule 4- 4 case of more than one Substituent 2- di 3 Tri 4 Tetra 5 Penta ### Image 9 Note - when di, tri, tetra are used for normal Substituents then these are not considered for alphabatical order: But when these are used for complex substituent then it is considered in alphabatical order 4 ethyl-2,3-dimethyl hexane Naming of complex substituent ( normal substituent) (complex substituent) Diagram of a 4-(1 methylethyl) heptane Diagram of a 4-(1 methylpropyl) hexane ### Image 10 Image contains diagrams of 5=(1-methylethyl) Diagram of (2 Bromo-5 ethyl-3-methyl-6 (1 methyl): proply) nonane X 5 thyl-3methyl (4, 1-dimethylethyl )octane 4 (11(dimethylethyl)-5 ethyl 3methy octane.

Then Select the multiple bond which have maxm n. of carbon Ruk 3- if above 3 rull Them Selt that caston chain as parent chan which contains more no of double bond rather than triple bond Rule 4 thove 3 rule fails then select that carbon chein on parent chain which contain mon ro 31 CH-CH3 Numbering Chain Multiple dond should but lowest locant numbers ### Image 12 Rule 2 when locant number is same from both end then numbering should be done from that end which gives lowest locant no double bond Rule 31 above two nales fails then select that numbering which gives lowest locant to subsitute C H Muthyl Hipta & S Dene Hepta 1 & Triene ### Image 13 3 ethyl - 4 methyl hexa -1, 5 dive Pet 2- one CH? - ( - CH?- CHg-C=CH 2. 11th and Hept 1, diene Gyne ### Image 14 - *Nomenclature of cyclic Compound - Bicyclo, spiro - Rule-1- - $ \bigtriangleup$ - cyclopropane - $ \Box$ - cyclobutane - A - cyclohexane - a - cyclopentane - $ \nearrow$ - 1-methylcyclopropane - $ \Box$ - 1,2-dimethylcyclobutane - $ \Box$ - 1,1-dimethyl cyclobutane - $\partial^{\text{3}}$ - 1,1,2-trimethylcyclobutane - - If more than one substituent, then follow alphabatical ordre $CH_{11}C^1$ <math> <mn>1</mn> </math>2 -bromo-2-chlorocyclobutane <math> <mn>1</mn> </math>32 BRO1<math> <mn>1</mn> </math> -Bromo-3 chlorocyclopentane. ### Image 15 Contains Organic Chemistry Diagrams Diagram of 1-ethyl -2- methyl cyclobutane Diagram of 1- Boromo -2- Chloro-3- Fluoro cylohexane Rula-a- 17. more than two substituent are present Then Follow lowest lock Rule Brom 2 ethyl-methyl cyclohexane 0.08 (13, 4-c 2 Bromo-1-chloro-4- Furo Cyclosane Bromo110 - iodo Cycksshe ### Image 16 Contains handwritten notes and diagrams Rule-4- In case of cyclic compound. parent chain is that chain which contains more on carbon. it may be cyclic or open chain) Bahubali Trick Rule & It both cycle & open chain have some coor corbon then cycle and be porent chain T 6 2 chlorent Hexane methyll propyl cyclopentone mathyl pentan ### Image 17 Diagram of Organic Chemistry Structures 4-cyclobutyl-2-cyclopenthyl hexane Cycloprop-theme Cyclobut-e-ene But 1.3 dine Cluropena 13deene Rule 3-F must contam Cycloent EthI - ene 4 Athyl 3.3 dimethy Lyclomer en 23 dimethyl Cyclopent-1-ene ### Image 18 1, 2-dimethylcuprop-lene 2-cyclobutyl pentane 1/2-dimethyl cyclo hen-lene 1035302 1-cyclopropyl cyclohexane diagram 592984 Bicudo [440] decan 33000 Bicydo [4.20 ] Octant Brydo 1 ### Image 19 Bicyclo [222] Octane 7 3 Bicyclo [321] octane.
