2015 AIPMT-II 1 question

1. 1 The p-Block Elements
   The variation of the boiling points of the hydrogen halides is in the order HF > HI > HBr > HCl. What explains the higher boiling point of hydrogen fluoride?
   A The bond energy of HF molecules is greater than in other hydrogen halides B The effect of nuclear shielding is much reduced in fluorine which polarises the HF molecule C The electronegativity of fluorine is much higher than for other elements in the group D There is strong hydrogen bonding between HF molecules
