Which of the following has strongest bond?

A$$HF$$
Correct Answer
B$$HCl$$
C$$HBr$$
D$$HI$$

Solution

Let's look at the bond enthalpy of hydrogen bonds of HF, H2O and NH3.
HF 10kcal/mol
H2O 7kcal/mol
NH3 2kcal/mol
Higher the bond enthalphy means higher the strength of bond,
So the correct option is [A].
