(c) 2 (d) 3

Answer 1

Answer:

(b) 4

There will be four such isomers.

Answer 2

Answer:

The correct answer is (B) 4.

Explanation:

There will four primary alcohol obtained from the chemical formula C5H11OH.

The carbon chain when added to the OH group the possible outcome will be.

1. Pentan-1-ol

2. 2-methylbutan-1-ol

3. 3-methylbutan-1-ol

4. 2,2 – dimethylpropan-1-ol

The primary alcohol means when hydroxyl group is attached to primary carbon atom.
