Question

Which of the following gives maximum value of enthalpy of physiolysis?

• A. \( \text{C}_2\text{H}_6 \)
• B. \( \text{Ne} \)
• C. \( \text{H}_2 \text{O} \)
• D. \( \text{H}_2 \)

Hint:

The enthalpy of physiolysis depends on the bond dissociation energy, which is highest in \( \text{H}_2 \text{O} \).

Answer 1

The Correct Option is C

Step 1: Enthalpy of physiolysis.
The enthalpy of physiolysis refers to the energy required to break bonds in a molecule. \( \text{H}_2 \text{O} \) has the highest bond dissociation energy among the given molecules.
Thus, the correct answer is (3).
