Question

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

Short answer

Answer

• Two stereogenic centers are present in the tetraalkylammonium salt.

• Structure of all possible stereoisomers

Step-by-step solution

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.

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.
