(a)

Interpretation Introduction

To determine: If the given compound is terpene.

Interpretation: If the given compound is terpene is to be stated.

Concept introduction: An isoprene unit is bunched of five-carbon atoms. In terpenes, the isoprene units are connected to each other in head to tail fashion. The head part of an isoprene unit is branched, whereas the tail part of an isoprene unit is un-branched.

(b)

Interpretation Introduction

To determine: If the given compound is aromatic.

Interpretation: If the given compound is terpene is to be stated.

Concept introduction: A compound is said to be aromatic when it follows (4n+2)π rule or its π-electrons are in conjugation with each other.

(c)

Interpretation Introduction

To determine: The products that results from the saponification of given compounds with aqNaOH.

Interpretation: The products that results from the saponification of given compounds with aqNaOH are to be stated.

Concept introduction: The formation of ester molecule from carboxylic acid and alcohol is known as esterification. The reverse of esterification is known as hydrolysis or saponification.
