Statement I: Acid strength increases in the order given as HF...
Statement I: Acid strength increases in the order given as
Statement II: As the size of the elements increases down the group, the bond strength of and HI decreases and so the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
Options
- ABoth Statement I and Statement II are true.
- BBoth Statement I and Statement II are false.
- CStatement I is correct but Statement II is false.
- DStatement I is incorrect but Statement II is true.
Correct answer
A. Both Statement I and Statement II are true.
Step-by-step solution
Acidic strength of hydracids increases in order
So, statement-I is true
The above order of acidic strength is due to decrease in bond strength. As the size of atom increases, bond length increases and bond strength decreases.
Thus, statement I and statement II are true
