Identify the longest continuous carbon chain in the molecule; this chain determines the parent alkane name.

Assign numbers to the carbon atoms in the longest chain to give the substituents the lowest possible numbers.

Use the assigned numbers to indicate the position of the side chains (substituents) attached to the parent chain.

Use prefixes like 'di-', 'tri-', 'tetra-' to indicate multiple identical substituents.

Arrange the names of substituents in alphabetical order (before the name of the parent chain).

Separate numbers with commas and separate numbers from substituent names with hyphens.

The name of an alkane depends on the number of carbons in the main chain.

Branched groups are named as alkyl groups. Ex. methyl, ethyl

Alkynes are more reactive than alkanes and alkenes due to the presence of a carbon-carbon triple bond.

Alkynes are more unsaturated than alkanes and alkenes because of the carbon-carbon triple bond.

Alkynes, when burned, produce a smoky, luminous flame, forming carbon dioxide and water.

CnH2n-2 + (3n-1)/2 O2 ⇌ nCO2 + (n-1) H2O

Alkynes react by adding atoms or groups to the carbon-carbon triple bond.

A reaction that releases heat to the surroundings.

Ethyne can be prepared from calcium carbide and water.

Ethyne is an alkyne, characterized by a triple carbon bond and undergoing addition and combustion reactions.

A hydrocarbon with single bonds between carbon atoms.

A hydrocarbon with a carbon-carbon double bond.

A hydrocarbon with a carbon-carbon triple bond.

A hydrocarbon with a benzene ring.

A compound with a hydroxyl group (-OH) attached to a carbon atom.

A compound containing a carbonyl group (C=O) at the end of a carbon chain.

A compound with a carbonyl group (C=O) in the middle of a carbon chain.

A compound with a carboxyl group (-COOH).

A compound with a carboxyl group (-COO) attached to an alkyl group.

A compound containing only carbon and hydrogen.

Biogas, primarily methane, is generated through anaerobic fermentation of organic materials like animal dung and plant waste.

A system that utilizes anaerobic fermentation to convert organic materials into biogas, a mixture of gases, mainly methane.

A laboratory experiment to produce methane gas from cow dung by mixing it with water, allowing it to ferment, and then collecting the gas released.

Identifying the presence of methane by testing the collected gas with a lighted splint, observing if it burns, and adding calcium hydroxide to observe any change.

Biogas offers benefits like saving on fuel (kerosene, wood, charcoal), reducing deforestation, and generating fertilizer residue.

A process of breaking down organic matter in the absence of oxygen, resulting in the production of biogas, primarily methane.

Biogas is a mixture of gases, predominantly methane (CH4), but may also contain other gases like carbon dioxide (CO2) and hydrogen sulfide (H2S).

The remaining material after biogas production can be used as a valuable fertilizer, enriching the soil with nutrients.

Benzene is represented by resonance structures, where two structures contribute equally to the actual structure, giving it a hybrid character.

The bonds in benzene are neither solely single nor double, existing as an intermediate state, making all carbon-carbon bonds equal in length and nature.

The six electrons in the benzene ring are delocalized, creating resonance and contributing to its stability.

Benzene's delocalized electrons make it more stable than alkenes, giving it a different chemical behavior.

Benzene primarily undergoes substitution reactions rather than addition reactions, unlike alkenes.

Benzene is a flammable, colorless, and volatile liquid with a characteristic odor, immiscible with water but miscible with non-polar solvents.

Benzene is used as a solvent for fats, gums, and rubber, and in the manufacture of dyes, drugs, and explosives.

Benzene is carcinogenic, meaning it can cause cancer.

Compounds originally believed to originate from living organisms and were thought to contain a special 'life force'.

A discredited concept that proposed living organisms contained a unique force that enabled the creation of organic compounds.

Friedrich Wöhler synthesized urea (an organic compound) from inorganic starting materials, proving that a 'life force' wasn't required for organic compound formation.

Specific groups of atoms within molecules responsible for their characteristic chemical behavior and reactions.

The study of carbon-containing compounds, including their structure, properties, and reactions.

The ability of carbon atoms to bond with each other to form long chains, rings, and branched structures.

Hydrocarbons containing only single bonds between carbon atoms. They contain the maximum number of hydrogen atoms possible for each carbon.
