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

Option C

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

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
