Which of the following compound can form hydrogen bonds?
CH4
NaCl
CHCl3
H2O
H2O can form hydrogen bonds. CH4 and CHCl3 are organic compounds having no oxygen while NaCl has the intra-ionic attraction in the molecule.
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
