Question: How many stereogenic centers are present in the following tetraalkylammonium salt? Draw all possible stereoisomers.

Short Answer

Expert verified

Answer

  • Two stereogenic centers are present in the tetraalkylammonium salt.
  • Structure of all possible stereoisomers

Step by step solution

01

Stereogenic centre

A Stereogenic centre has tetrahedral geometry in which carbon is bonded to four different groups.

The nitrogen atom of the quaternary ammonium salt is a Stereogenic centre when the nitrogen is surrounded by four different groups.

02

Stereogenic centre and possible stereoisomers 

The Stereogenic centres present in the compound are:

Stereo centers in the given molecule

For n Stereogenic centres, the maximum possible stereoisomers are 2n.

Given tetraalkylammonium salt has two Stereogenic centres.

Hence, the maximum possible stereoisomers are four.

All possible stereoisomers
