Question

Three organic compounds A, B and C have the following molecular formulae:  C₄H₈O

Which molecular formula can represent an aldehyde as well as a ketone? Write the names and structural formulae of the aldehyde and ketone represented by this molecular formula.

Answer 1

Compound 'C' (C₄H₈O), represents the molecular formula of an aldehyde as well as a ketone. The aldehyde represented by this formula is butanal (C₃H₇CHO).
The ketone represented by this formula is butanone (CH₃COCH₂CH₃).
Their structural formulae are as follows:
