Question

The optically active compound (X) on treatment with $NaN{O}_2/HCl$ gives:

• A. $1^o$ alcohol with retention of configuration
• B. $2^o$ alcohol with inversion of configuration
• C. raecemic mixture of $2^o$ alcohols
• D. raecemic mixture of $1^o$ alcohols

Answer 1

The correct option is A $1^o$ alcohol with retention of configuration

Retention of configuration inversion of configuration is the property of product due to reaction mechanism followed for eg in $r{x}^n$ mechanism like $S{N}^2$ the attacking species gets from behind and the product have opposite orientation from the reaction.
