Question

(d) h₃c—hc—ch₂—c—oh
ch₃
ester
alkene
alkane
aromatic
ketone
alcohol
amine
carboxylic acid
alkyne
aldehyde
ether

Explanation:

The compound has a -COOH functional group. A carboxylic acid is an organic compound that contains a carboxyl group (-COOH). An ester has -COO- (where the O is bonded to another carbon chain). An alkene has a C=C double bond. An alkane has only single C - C bonds. An aromatic compound has a benzene - like ring. A ketone has a C=O group (carbonyl) with two carbon groups attached to the carbonyl carbon. An alcohol has -OH (hydroxyl) group attached to a non - carbonyl carbon. An amine has a -NH₂ (or related) group. An alkyne has a C≡C triple bond. An aldehyde has a C=O group (carbonyl) with at least one hydrogen attached to the carbonyl carbon. An ether has an O atom between two carbon chains (R - O - R').

Answer:

carboxylic acid
