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.
Solution
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:
