Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following substances are structural isomers of each other?I. CH3(CH2)3CH3II. (CH3)2CHCH3III. CH3CH(CH3)CH2CH3
A
I and II only
B
I and III only
C
II and III only
D
I, II and III
Explanation: 

Detailed explanation-1: -CH3−CH=CH−CH3 and CH3−CH2−CH=CH3 are position isomers as they have the same molecular formula (C4H9) and the only difference is in the position of unsaturation.

Detailed explanation-2: -Expert Answer The molecular formula, CH3CH2OCH3 consists of an ether functional group whereas the molecular formula, CH3CH2CH2OH consists of an alcohol functional group. It is observed that the above-given isomers differ in their functional groups. Thereby, they are referred to as functional isomers.

Detailed explanation-3: -As these both compounds have different functional groups so they exhibit functional isomerism.
