Assertion (A) Deoxyribose, C(5)H(10)O(4)...

Assertion (A) Deoxyribose, `C_(5)H_(10)O_(4)` is not a carbohydrate.
Reason (R) Carbohydrates are hydrates of carbon so compounds which follow `C_(x)(H_(2)O)_(y)` formula are carbohydrates.

A

If both assertion and reason are true , and is the true explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If asseration is true , but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Correct assertion : Deoxyribose `(C_5H_10O_4)` is a carbohydrate.
Correct reason : Optically active polyhydroxyaldehydes or ketones or substances which give these on hydrolysis are called carbohydrates.
