AIPMT PRELIMS 2001 Chemistry Enthalpy MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Enthalpy of CH₄ + 1/2 Ω₂ → CH₃OH is negative. If enthalpy of combustion of CH₄ and CH₃OH and x and y respectively. Then which relation is correct : -
A
x > y
B
x < y
C
x = y
D
x ≥ y
Correct Answer
Option B
Detailed Explanation
The reaction CH₄ + 1/2 Ω₂ → CH₃OH is exothermic, meaning it releases heat. Therefore, the enthalpy of combustion of CH₄ (x) is greater than that of CH₃OH (y), so x < y.
