A compound containing only carbon, hydrogen and oxygen has molecular mass of 44.0. On complete oxidation, it is converted into a compound of molecular mass 60.0. The compound is :

A

An aldehyde

B

An acid

C

An alcohol

D

An ether

Text Solution

Verified by Experts

The correct Answer is:
A
On complete oxidation the obtained compound shows increament in molecular weight of only 16. It means only one oxygen atom is added here. This condition is fulfilled by only aldehyde which one oxidation givens acid.
`RCHO overset([O])rarr RCOOH` Hence, original compound must be `underset("mol.wt."44)(CH_(3)CHO) overset([O])rarr underset("mol.wt."60)(CH_(3)COOH)`
