Statement I : Acid strength increases in the order given as . Statement II : As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCl, HBr 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.
Both statement I and Statement II are true
Both Statement I and Statement II are false
Statement I is correct but statement II is false
Statement I is incorrect but Statement II is true
As we move down the group in the periodic table, the atomic size of the halogen increases. This leads to a decrease in the bond dissociation energy of the H-X bond. Consequently, the acid strength increases in the order . Both statements are correct.
