Question

What is the correct order of C-X bond strength in CH₃X?

पर्याय

• CH₃I > CH₃Br > CH₃Cl > CH₃F

• CH₃CI > CH₃Br > CH₃I > CH₃F

• CH₃F > CH₃Br > CH₃CI > CH₃I

• CH₃F > CH₃CI > CH₃Br > CH₃I

Answer 1

CH₃F > CH₃CI > CH₃Br > CH₃I

Explanation:

The size of halogen atom increases from F to I, which increases the C-X bond length. Larger the size, greater is the bond length and weaker is the bond formed.

Hence the order of C-X bond strength in CH₃X is, CH₃F > CH₃CI > CH₃Br > CH₃I.
