The order of boiling point of NH3, H2O, HF and PH3 is
H2O > HF > NH3> PH3
H2O > HF > PH3> NH3
H2O >NH3>HF > PH3
PH3> NH3> HF > H2O
H2O has higher boiling point than NH3 & HF as it has more number of hydrogen bonds and all are broken at 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 boiling point of NH3 H2O and HF are exceptionally higher explain
Out of NH3, H2O and HF, which has the highest magnitude of Hydrogen bonding:
