How many of the following show(s) H-bonding. (ii) H2O (iii) CH3OH (iv) HF (v) NH3

Question

How many of the following show(s) H-bonding. 

(i)

(ii)   H₂O

(iii)  CH₃OH

(iv)  HF

(v)   NH₃

(vi) 

(vii)  

(viii)   C₂H₆

Answer 1

Correct answer is: 6

The system having suitable electropositive pole H and suitable electronegative pole can show H-bonding. Suitable positive pole H: \(F-H,\) , suitable negative pole: Electronegative element F, O, N with sufficient negative charge.

Hence H₂O, CH₃OH, HF and NH₃ can show intermolecular H bonding and

Can show interamolecular H bonding.
