Question

Identify each of the following as the $\alpha$or $\beta$isomer:

Short answer

(a) As the OH group on the carbon atom is upward it is $\alpha$isomer

(b) As the OH group on the carbon atom is downward it is$\beta$ isomer

Step-by-step solution

Part (a) Step 1 : Given information

We have to identify the given compounds as $\alpha$or $\beta$isomers.

Part (a) Step 2 : Explanation

The -OH group on carbon $1$is down hence it is $\alpha$isomer

Part (b) Step 1 : Given information

We have to identify the given compound as $\alpha$or $\beta$isomer.

Part (b) Step 2 : Explanation

The -OH group on carbon $1$is up hence it is$\beta$isomer
