Question

The empirical formula of a compound of molecular mass is $C{H}_{2}O$. The molecular formula of the compound is:

• A. $C_2{H}_4{O}_2$
• B. $C_4{H}_8{O}_4$
• C. $C_3{H}_6{O}_3$
• D. all of these

Answer 1

The correct option is D all of these

Empirical formula of a compound is the simplest positive integer ratio of atoms present in a compound.

Here, Empirical formula:- $C{H}_{2}O$

Ratio of $C,H$ and $O=1:2:1$

In compound $A,B$ & $C$, Carbon,Hydrogen and Oxygen are present in $1:2:1$ respectively

(A) $C_2{H}_4{O}_2⟶2:4:2⟶1:2:1$

(B) $C_4{H}_8{O}_4⟶4:8:4⟶1:2:1$

(C) $C_3{H}_6{O}_3⟶3:6:3⟶1:2:1$

So, the answer is option D.
