(i) (ii) (iii)

• A. Chain Functional position Isomersim Isomersim Isomersim
• B. Functional Chain position Isomersim Isomersim Isomersim
• C. Position Chain Functional Isomersim Isomersim Isomersim
• D. Chain Position Functional Isomersim Isomersim Isomersim

Answer 1

Answer: (A)

Chain Functional position

Isomersim Isomersim Isomersim

Answer 2

(i) $CH_{3}CH_{2}CH_{2}CH_{2}CH_{2}OH$ and

(ii) $CH_{3}CH_{2}OHandCH_{3}OCH_{3}$ $$ functionalisomersim$$

(iii) $CH_{3}CH_{2}CH_{2}CH_{2}OHandCH_{3}\underset{OH}{\underset{|}{CH}} - CH_{2}CH_{3}$$$Positionisomersim$$
