Question

Assertion:
All naturally occuring $\alpha -$ amino acids are optically active.
Reason:
Most naturally occurring amino acids have D - configuration.

• A. Both assertion and reason are correct and reason is the correct explanation for assertion.
• B. Both assertion and reason are correct but reason is not the correct explanation for assertion.
• C. Assertion is correct but reason is incorrect.
• D. Both assertion and reason are incorrect.

Answer 1

The correct option is D Both assertion and reason are incorrect.

Glycine, the first member of $\alpha$ amino acids, is optically inactive.
Most naturally occuring amino acids have L-configuration.
Hence option (d) is correct.
