Assertion:`S_(N)2` reactions proceed with inversion of configuration
Reason: `S_(N)2` reactions oC Cur in one step .

S_N2 reaction occurs with inversion of configuration/ racemisation.

S_(N)2 reaction occurs with "inversion of configuration" // "racemisation" .

S_(N)2 reaction occurs with "inversion of configuration" // "racemisation" .

Assertion:- SN^(2) reaction proceeds with inversion of configuration. Reason:- The attack of nucleophile occurs from a side opposite to the halogen atom resulting in inversion of configuration.

Assertion: Hydrolysis of (-)-2- bromooctane proceeds with inversion of configuration. Reason: This reaction prioceeds through the formation of a carbocation.
