Question

Choose the correct statement for the given compounds:

• A. (a) and (b) are not isomers.
• B. (a) and (b) are functional isomers.
• C. (a) and (b) are chain isomers.
• D. (a) and (b) are positional isomers.

Answer 1

The correct option is B (a) and (b) are functional isomers.

(a) is butan-1-al and (b) is butan-2-one
Both (a) and (b) have same molecular formula i.e. $C_4{H}_{8}O$
Aldehyde and ketone are examples of functional isomers.
