Question 1 Report

Catalytic hydrogenation of alkenes produces compounds with the general formula

C_nH_2n+1 OH

C_nH_2n+1

C_nH_2n+2 Correct answer

C_nH_2n-2

C_x(H₂O)_y

Answer Details

The correct answer is (c) C_nH_2n+2. When alkenes undergo catalytic hydrogenation, each double bond in the molecule is converted into a single bond, and two hydrogen atoms are added to the molecule. This process is a type of addition reaction, and the general formula of the resulting compounds is C_nH_2n+2. Therefore, is the correct answer.
