An organic compound X reacts with excess acidified potassium dichromate(VI) to form compound Y, which reacts with sodium carbonate to produce CO2 (g).

What is a possible formula for compound X?

A. CH3CH2COOH
B. CH3CH2CH2OH (This is the answer)
C. CH3CH(OH)CH3
D. (CH3)3 COH

I need some help in figuring out why B is correct, thanks.

-
A is already a carboxylic acid so it'll not be further oxidized (reject)
C is a secondary alcohol it'll be oxidized to a ketone but ketones doesn't react with sodium carbonate as the aren't acidic. (reject)
D is a tertiary alcohol it'll not be oxidised (reject)
remaining B which is the a primary primary alcohol which will be oxidized to an acid therefore reacting with sodium carbonate to produce CO2. (accepted)
Eqn. CH3CH2CH2OH ---[O]----> CH3CH2COOH
