Question

Hydrogen bonds are formed in many compounds e.g., H2O, HF, NH3 . The boiling point of such compounds depends to a large extent on the strength of hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points of above compounds is :
(i) HF > H2O > NH3
(ii) H2O > HF > NH3
(iii) NH3 > HF > H2O
(iv) NH3 > H2O > HF
plz give explaination as well

Answer 1

ans is (2) H2O>HF>NH3
it is due to less strong H bonding in NH3 and zig zag structure of HF...

Answer 2

option no 2 is correct......
