Question

What is the major organic product obtained from the reaction of (R)-2-bromohexane with sodium cyanide/acetone

Answer 1

Option C

Step-by-step explanation:

The complete question is

What is the major organic product obtained from the reaction of

(R)-2-bromohexane with sodium cyanide/acetone?

A) ) trans-2-pentene

B) ( S)-2-Methylpentanenitrile

C) ( S)-2-Methylhexanenitrile

D) (plus or minus)-2-Methylpentanenitrile

Solution

This is an inversion reaction in which (R) 2 Bromohexane convert into (S) -2 – methyl hexane in the presence of Acetone and NaCN.

The reaction occurs through the SN2 mechanism and there is inversion of confiruration

Hence, option C is correct
