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
