Which of the following gives correct arrangement of compounds involved based on their bond strength?

Options

A. HF gt HCl gt HBr gt HI
B. HI gt HBr gt HCl gt HF
C. HF gt HBr gt HCl gt HI
D. HF gt HCl gt HBr gt HI

Answer

A

Explanation

Shorter the bond, stronger the bond. Smaller the atomic (size of one of the atom, other being the same) shorter is the bond length. Atomic radii of halogens are in the order : F lt Cl lt Br lt I
Therefore bond length of HX is in the order : HFlt HCl lt HBr lt HI
Bond strength is in the order HF gt HCl gt HBr gt HI
