Q. Oxygen containing organic compound upon oxidation forms a carboxylic acid as the only organic product with its molecular mass higher by 14 units. The organic compound is
A) An aldehyde
B) A primary alcohol
C) A secondary alcohol
D) A ketone
Explanation
(b)
Because the difference in mass between $–CH_{2}OH$ group and $–COOH$ group is 14, thus the compound which undergoes oxidation is a primary alcohol. (-$CH_{2}OH$ is the functional group of primary alcohols).
$\ \ \ RCH_{2}OH\ \ \ \ \ \rightarrow \ \ \ RCOOH$
(R+31) (R+45)
Primary alcohol acid
