Question

What is correct order of C - X bond strength in CH₃ - X?

पर्याय

• CH₃F > CH₃Cl > CH₃Br > CH₃I

• CH₃Cl > CH₃Br > CH₃l > CH₃F

• CH₃l > CH₃Br > CH₃Cl > CH₃F

• CH₃F > CH₃Br > CH₃Cl > CH₃I

Answer 1

CH₃F > CH₃Cl > CH₃Br > CH₃I

Explanation:

As the size of halogen atom (X) increases, the

C - X bond length increases and hence, the C - X bond strength decreases.

Since, the order of size of halogen atom is,

F < Cl < Br < I

Thus, the order of C-X bond strength is,

C - F > C - CI > C - Br > C - 1

The correct order of C - X bond strength in CH₃ - X is,

CH₃ - F > CH₃ - Cl > CH₃Br > CH₃l
