Question

The molecular weight of an oxide of Hydrogen is $34$. Therefore the number of covalent bonds in its molecule are:

• A. $4$
• B. $5$
• C. $2$
• D. $3$

Answer 1

The correct option is D $3$

Oxide of hydrogen,
$H_{2}O$ $H_2{O}_2$
M.W-$16$ M.W-$34$
In $H_2{O}_2$ , three covalent bonds are present.
