Question

The correct sequence of bond enthalpy of 'C-X' bond is

(1) CH₃–F < CH₃–Cl < CH₃–Br < CH₃–I

(2) CH₃–F > CH₃–Cl > CH₃–Br > CH₃–I

(3) CH₃–F < CH₃–Cl > CH₃–Br > CH₃–I

(4) CH₃–Cl > CH₃–F > CH₃–Br > CH₃–I

Answer 1

Correct answer is (2).

Correct sequence of bond enthalpy of C–X bond is

CH₃–F > CH₃ – Cl > CH₃ – Br > CH₃ – I
