NEET2007ChemistryGeneral Organic ChemistryActual
Assertion : The lactic acid shows the geometrical isomerism. Reason : Lactic acid has carbon-carbon double bond.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
D. If both assertion and reason are false.
Step-by-step solution
2-Hydroxy propanoic acid is known as lactic acid. It has following structure- It has no carbon-carbon double bond and hence cannot show geometrical isomerism. However, it shows optical isomerism due to the presence of a chiral carbon atom.
