Question:
Which of the following compounds shows optical isomerism?
Which of the following compounds shows optical isomerism?
Updated On: Aug 1, 2022
- $ CH_{3}-CH-BrCOOH $
- $ CH_{2}OHCH_{2}-COOH $
- $ COOHCHBr-COOH $
- $ CH_{2}Br-CH_{2}-COOH$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Optical isomerism is exhibited by asymmetric compounds. Compounds having chiral carbon atom are usually asymmetric and exhibit optical isomerism.
$ CH_{3}\overset{*}{C}H(Br)COOH$ , due to the presence of chiral carbon atom, exhibits optical isomerism.
[$ \overset{*}{C}=$ chiral carbon, the carbon four valencies of which are attached with four different groups.]

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
