Chemistry Question on Hydrogen Bonding
The correct order of increasing intermolecular hydrogen bond strength is
A
HCN<H2O<NH3
B
HCN<CH4<NH3
C
CH4<HCN<NH3
D
CH4<NH3<HCN
Answer
CH4<HCN<NH3
Explanation
Solution
Due to high difference in electronegativity of H and N the H−bond strength of NH3 is highest.
There is no H−bond in CH4.
CH4<HCN<NH3
Hence, correct option is (C): CH4<HCN<NH3
