Question

Which of the following is not a property of $H_2{O}_2$?

• A. The boiling point of $H_2{O}_2$ is lesser than that of water
• B. $H_2{O}_2$ acts as bleaching agent
• C. Its melting point is lesser than that of water
• D. It is used as an antiseptic with the name perhydrol

Answer 1

Answer: (A)

The boiling point of $H_2{O}_2$ is lesser than that of water

The boiling point of $H_2{O}_2$ is greater than that of water.

The boiling point of $H_2{O}_2$ at 1 atm pressure is $151$ ${}^{0}C$. The boiling point of water at $1$ atm pressure is $100$ ${}^{0}C$. The extent of hydrogen bonding (and the degree of association) in the case of $H_2{O}_2$ is much higher than that in the case of water.

Hence, option A is the answer.
