Interpretation:
The structure is to be drawn, and the correct IUPAC name for the given trivial name is to be provided.
Concept introduction:
Most of the trivial names of
For a straight chain aldehyde, the carbonyl carbon gets number one. For cyclic aldehydes, the carbonyl carbon cannot be the part of the ring, and thus, it must be present outside the ring.
To write the IUPAC name of a compound, first it is important to determine the highest-priority functional group present that requires a suffix referring to Table E-1. The suffix al is used for aldehydes. Then the main chain or ring is to be determined that contains the highest-priority functional group. The next step is to number the main chain or ring such that carbon atoms involving the highest-priority functional group receive the lowest possible numbers. The locator number for the highest-priority functional group is written immediately before the suffix, unless redundant. All other

Concept introduction:
Most of the trivial names of aldehydes are derived from the analogous carboxylic acids.

All other functional groups in the molecule are treated as substituents and appear in the name as a prefix. Prefixes such as di, tri, tetra, etc., are used to indicate the number of identical substituents attached. The substituents are named in the alphabetical order.
