The racemic -2,3- dibromopentane on reaction with KI in acetone give :

A partially racemised (+2) 2-Bromooctane on reaction with aq. NaOH in acetone gives an alcolhol with 80% inversion and 20% racemisation . Find out the rate expression of the reaction.

A partially racemised (+) - 2-bromo-octane (2^@ RX) on reaction with aq. NaOH in acetone gives an alcohol with 80 % inversion and 20 % racemisation. What is the percentage of back-side attack ?

In the following questions, a statement of assertion (A) is following by a statement of reason (R ) A : Meso -2, 3 - dibromobutane on reaction with Zn/ether gives trans but -2 ene . R : Zn/ether gives anti elimination .

What happens when (+)2- iodobutane is treated with Nal in acetone?

Calculate the percentage of SN^(-1) product, if (R )-2 -Chloro butane on reaction with NaOH//H_(2)O and acetone gives 98% inverted product.

Statement-I: Optically active 2-idoibutane on treatment with NaI in acetone undergoes racemisation. Because Statement-II: Repeated Walden inversions on the reactant and its product evantually gives a racemic mixure.

The Grignard reagent, on reaction with acetone, forms :

Assertion : trans -2- Butene on reaction with Br_(2) gives meso -2,3- dibromobutane. Reason : The reaction involves syn - addition of bromine.
