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

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

Acetone on reaction with chlorine gives normally

Assertion: Optically active 2-iodobutane on treatment with Nal in acetone undergoes racemization. Reason : Repeated Walden inversions on the reactant and its product eventually gives a racemic mixture.

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 .

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 .

Iodoform is obtained by the reaction of acetone with hypoiodite but not with iodide I on. Explain. (b) Optically active 2-iodobutane on treatment with Nal in acetone gives a product which does not show optical activity. Why?

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