Q. Which type of isomerism is shown by propanal and propanone?
A) Functional group
B) Metamerism
C) Tautomerism
D) Chain isomerism
Explanation
(a)
When two compounds have similar molecular formula but differ in the functional group then the isomerism is called functional group isomerism i.e.,
O
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \parallel$
$CH_{3}CH_{2}CHO\ and\ CH_{3}.CCH_{3}$
