Account for the following: The acidic strength decreases in the order HCl gt H_2S gt PH_3 |

Answer» Solution :Acidic STRENGTH of a hydrogen compound depends UPON the electronegativity difference between hydrogen and the second element. Greater the electronegativity difference, greater the acidic strength. Electronegativity DECREASES in the order `CL(3.2) GT S (2.44) gt P(2.1)` Consequently , the acidic strength also decreases in the order `HCl gt H_2S gt PH_3` |
