(a) Carbohydrates derive its name from the hydrates of carbon

(b) The general formula of all carbohydrates is Cx(H20)y

(c) Carbohydrates are defined as optically active polyhydroxy aldehydes or ketones or the compounds that produce such units on hydrolysis

(d) Glyceraldehyde is the smallest carbohydrate

The question was asked in my homework.

Question is taken from Biomolecules-1 topic in division Biomolecules of Biology – Class 11

Answer 1

Right choice is (b) The general formula of all carbohydrates is Cx(H20)y

Easiest explanation: Carbohydrates derive its name from the hydrates of carbon. Earlier, carbohydrates are assumed to obey the formula Cx(H20)y but later most of the carbohydrates. Carbohydrates are defined as optically active polyhydroxy aldehydes or ketones or the compounds that produce such units on hydrolysis. Glyceraldehyde is the smallest carbohydrate.
