NEET Chemistry Covalent Bond MCQ Question
Calculate the average bond enthalpy for the O-H bonds in a water molecule given that and .
464.5 kJ mol⁻¹
502 kJ mol⁻¹
427 kJ mol⁻¹
464 kJ mol⁻¹
Correct Answer
Detailed Explanation
The average bond enthalpy is calculated by dividing the total bond dissociation enthalpy by the number of bonds broken: (502 + 427) / 2 = 464.5 kJ mol⁻¹.
