( II ) Bond dissociation enthalpy order of HX is H-F > H-Cl > H-Br > H-I

Easy

A

I and II both are true
B

I is true and II is false
C

I is false and II is true
D

I and II are false

Solution

In HX, stability decreases down the group because , bond dissociation enthalpy order of HX is H-F > H-Cl > H-Br > H-I
