Which of the following is(are) CORRECT decreasing order(s) of boiling point?
Question 04
Hydrogen bonds are formed in many compounds e.g., H2O, HF, NH3. The boiling point of such compounds depends to a extent on the strength of hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points above compounds is
(a) HF>H2O>NH3
(b) H2O>HF>NH3
(c) NH3>HF>H2O
(d) NH3>H2O>HF
The order of boiling point of NH3, H2O, HF and PH3 is
