Question

(a) $h_3c - ch_2 - hc - ch_2 - oh$ $|$ $ch_3$ ether alcohol amine alkene aromatic alkane carboxylic acid ketone aldehyde ester alkyne

Explanation:

An alcohol is an organic compound that contains a hydroxyl (-OH) functional group. In the given compound \(H_3C - CH_2 - HC(CH_3)-CH_2 - OH\), the presence of the -OH group indicates it is an alcohol. An ether has an -O- group between two carbon atoms (\(R - O - R'\)). An amine has a -NH₂, -NHR, or -NR₂ group. An alkene has a \(C = C\) double bond. An aromatic compound has a benzene - like ring structure. An alkane has only \(C - C\) and \(C - H\) single bonds. A carboxylic acid has a -COOH group. A ketone has a \(C = O\) group with two alkyl groups attached to the carbonyl carbon. An aldehyde has a \(C = O\) group with one alkyl group and one hydrogen attached to the carbonyl carbon. An ester has a -COO- group. An alkyne has a \(C\equiv C\) triple bond. Since the compound has a -OH group, it is an alcohol.

Answer:

alcohol
