The structural formula gives a graphical representation of the arrangement of atoms in the molecule. Here, acetamide forms the backbone of the structure. Acetamide is derived from acetic acid by the exchange of hydroxyl group by the NH₂ group. So replace the OH group from the structural formula of acetic acid by NH₂ get the structural formula of acetamide.

N-cyclohexylacetamide indicates that the cyclohexyl group is attached to the nitrogen atom in acetamide. So replace one hydrogen from the acetamide by the cyclohexane group.

The structural formula represents which all atoms are connected through bonds in the molecule. Methanoate indicates an ester group's presence because the suffix -oate is used for an ester group. Notably, the ester is derived from the parent carboxylic acid that contains one carbon, methanoic acid. 

1-Propane is an alkane that contains three carbon atoms arranged in a linear fashion. When one of the terminal hydrogen of 1-propane is removed, the resultant structure is termed as 1-propyl and the substitution of a methyl group at the terminal carbon of 1-propyl group yields 1-propyl methyl fragment. 

Since the compound is an ester derived from methanoic acid, the 1-propyl methyl group should be bonded to the oxygen by replacing a hydrogen of the OH group.

The structural formula represents which all atoms are connected through bonds in the molecule. Butanoate indicates the presence of an ester group having four carbon atoms because the suffix -oate is used for an ester group and the base name but- shows the number of carbon atoms. 

The name cyclobutyl indicates that the alkane ring structure with four carbon atoms fused together. Draw four carbon atoms in a square type structure.

The parent carboxylic acid contains four carbon atoms is the butanoic acid. Repalce the hydrogen of the OH in the carboxylic unit, by the cyclobutyl group. The resultant structure obtained as a ester with -CO-O- linkage.

The suffix indicates that the functional group present is imide, where two acyl groups are attached to the nitrogen atom. Succinimide is a five-membered ring with an imide functional group. 

In 1-methylheptyl, the base name heptyl indicates the parent alkane with the seven carbon arranged in a linear fashion. Moreover, the methyl group is attached at the first position of the carbon chain to yield 1-methylheptyl unit. Draw the seven carbon atoms as a long chain and bond a methyl group at C1 position. 

Finally, replace the hydrogen of the succinimide by the 1-methylheptyl group to get the structural formula.

The structural formula gives a graphical representation of the arrangement of atoms in the molecule. It shows which all atoms are connected through bonds. Adipate is derived from adipic acid, a six carbon di carboxylic acid, by the abstraction of two acid protons. The prefix di- indicates that there are two ethyl substituents and are attached to the adipate resulting in the formation of an ester linkage (-O-CO-). 

The structural formula gives a graphical representation of the arrangement of atoms in the molecule. The suffix -amide indicates the presence of an amide functional group. The basename prop shows that there are three carbon atoms in the chain. The number indicates the position of the amino substituent. That is, the amino group is added to the second carbon atom of the propyl chain.
