Arrange the following alkyl halide in increasing order of bond enthalpy of RX CH_(3)Br, CH_(3)F, CH_(3)Cl,CH_(3)I.

Arrange the following alkyl halide in increasing order of bond enthalp

1.	Arrange the following alkyl halide in increasing order of bond enthalpy of RX CH_(3)Br, CH_(3)F, CH_(3)Cl,CH_(3)I.
Answer» SOLUTION :The bond strength of C-X bond decreases form C-F to C-I in `CH_(3)-X`. Increasing order of bond enthalpy. <BR> `CH_(3)I lt CH_(3) Br lt CH_(3)Cl lt CH_(3)F`.
