- The molecular formula C4H9Br has 4 structural isomers
- The molecular formula C5H12 has 3 structural isomers
Leaf Alcohol (Compound J)
- Compound J is also known as leaf alcohol, with the structural formula CH3CH2CH=CHCH2CH2OH
- The E isomer of J is responsible for the smell of freshly cut grass
- Dehydration of J using concentrated sulfuric acid forms a product with a specific skeletal formula
Isooctane (C8H18)
- Isooctane is a branched-chain hydrocarbon that burns smoothly in car engines
- The IUPAC name for isooctane can be determined from its skeletal formula
- Isooctane has a specific 13C NMR spectrum with a certain number of peaks
- Isooctane can be formed through the thermal cracking of an alkane with 20 carbon atoms, accompanied by propene and ethene
Thermal Cracking
- Thermal cracking is a reaction where a large molecule breaks down into smaller molecules, often with the application of heat
- The products of thermal cracking, such as isooctane, propene, and ethene, demonstrate the characteristics of thermal cracking
Monochloro Isomers of Isooctane
- Isooctane can form several monochloro isomers, with one of them existing as a pair of optical isomers
