Question

Assertion:The lactic acid shows the geometrical isomerism.

Reason: Lactic acid has carbon-carbon double bond.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (d) A and R are false

Explanation:

2-Hydroxy propanoic acid is known as known as lactic acid. It has the 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.
