MCQ
Which type of isomerism is shown by propanal and propanone
  • ✓
    Functional group
  • B
    Metamerism
  • C
    Tautomerism
  • D
    Chain isomerism
✓

Answer

Correct option: A.
Functional group
a
(a) When two compounds have similar molecular formula but differ in the functional group then the isomerism is called functional group isomerism i.e. $C{H_3}C{H_2}CHO$ and $C{H_3}.\mathop {\mathop C\limits^{||} }\limits^O \,C{H_3}$.
