Question

Assertion (A) compound containing -CHO group are easily oxidised to corresponsing carboxylic acids
Reason (R) : Carboxylic acids can be reduced to alcohols by treatement with `LiAlH_(4)`
A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false.
D. If assertion is false but reason is true.

Answer 1

Correct Answer - D
The melting point of an aliphatic carboxylic acid containing an even number of carbon atoms is higher than the next higher homologue containing odd number of carbon atoms. In this way the M.P. of aliphatic follow a regular pattern but not vary smoothly. Carboxylic acid reduced by HI in presence of red P at 473K.
