Question

(f) h₃c—hc—c=c—ch₃
alkyne
alkane
alcohol
amine
ketone
alkene
ester
aldehyde
carboxylic acid
aromatic
ether

Explanation:

• Alkynes have \(C\equiv C\) (carbon - carbon triple bonds).
• Alkanes have only \(C - C\) (carbon - carbon single bonds).
• Alcohols have \(-OH\) (hydroxyl) functional groups.
• Amines have \(-NH_{2}\) (amino) functional groups.
• Ketones have \(R - CO - R'\) (carbonyl groups between two carbon groups).
• Alkenes have \(C = C\) (carbon - carbon double bonds).
• Esters have \(R - COO - R'\) functional groups.
• Aldehydes have \(R - CHO\) (carbonyl group at the end of a carbon chain).
• Carboxylic acids have \(R - COOH\) functional groups.
• Aromatic compounds have a benzene - like ring structure.
• Ethers have \(R - O - R'\) functional groups.

The given compound has a \(C = C\) (carbon - carbon double bond), which is characteristic of alkenes.

Answer:

alkene
