In H O F , the O − H bond length is 96 p m while in H O C l, the O − H bond length is 97 p m and so H O F is more acidic than H O C l. Share. WebbSolution. The reason for the less acidic nature of H 2 S than H 2 Te. On moving from top to bottom in the group the size of the atom increases. With the increase in the size of the atom, there is a decrease in ionization enthalpy. As ionization enthalpy decreases the dissociation of the bond becomes easy. In the case of H 2 Te (Hydrogen telluride): tarara 316WebbSolution. Verified by Toppr. Because of decrease in bond dissociation enthalpy, acidity of hydrides increases down the group.
