Q. The correct sequence of bond enthalpy of 'C-X' bond is:
A) $CH_3-F > CH_3-Cl > CH_3-Br > CH_3-I$
B) $CH_3-F < CH_3-Cl > CH_3-Br > CH_3-I$
C) $CH_3-Cl > CH_3-F > CH_3-Br > CH_3-I$
D) $CH_3-F < CH_3-Cl < CH_3-Br < CH_3-I$
Explanation
[Solution] C-X bond length increases from F to I, so bond enthalpy decreases: C-F > C-Cl > C-Br > C-I. Answer (1).
