Step-by-step solution

(a) N-Cyclohexylacetamide

N-Cyclohexylacetamide is an acetamide with a cyclohexyl group attached to the nitrogen atom. Here are the steps to draw the structural formula for N-cyclohexylacetamide: 1. Draw a cyclohexane ring. 2. Attach an amide group with two carbons bonded to the nitrogen atom. The first carbon bond to the nitrogen atom and the second carbon is bound to the first carbon by a single bond. This structure represents the acetamide, with the nitrogen atom combining to the cyclohexane ring.

(b) 1-Methylpropyl methanoate

1-Methylpropyl methanoate is an ester with the following structure: 1. Draw a methanoate group (\(\mathrm{COOCH_3}\)). 2. Attach a 3-carbon chain with a methyl group on the first carbon to the first oxygen of the methanoate group.

(c) Cyclobutyl butanoate

Cyclobutyl butanoate is an ester with the following structure: 1. Draw a butanoate group (\(\mathrm{COOC_3H_7}\)). 2. Replace the hydrogen atom on the first carbon of the butanoate group with a cyclobutane ring.

(d) N-(1-Methylheptyl)succinimide

N-(1-Methylheptyl)succinimide is an imide with the following structure: 1. Draw a succinimide ring, which is a 5-membered ring containing a nitrogen atom and an oxygen atom. 2. Replace the hydrogen atom on the nitrogen atom with a 7-carbon chain that has a methyl group on the first carbon.

(e) Diethyl adipate

Diethyl adipate is an ester with the following structure: 1. Draw an adipate group, which is hexanedioic acid (\(\mathrm{HOOC(CH_2)_4COOH}\)). 2. Replace both hydrogen atoms on the carboxyl groups with an ethyl group (\(\mathrm{C_2H_5}\)).

(f) 2-Aminopropanamide

2-Aminopropanamide is an amide with an amino functional group in the \(\mathrm{\beta}\)-position: 1. Draw a 3-carbon chain called propanamide (\(\mathrm{H_2NCOCH_2CH_3}\)). 2. Replace one hydrogen atom on the second carbon with an amine group (\(\mathrm{-NH_2}\)).
