Explain why inspite of nearly the same electronegativity, nitrogen forms hydrogen bonding while chlorine does not.
Explanation Nitrogen is a member of group 15 and second period. And chlorine is member of group 17 and third period thus; chlorine has an extra shell and due to this size of chlorine is larger than of nitrogen. Due to smaller size of nitrogen it also has higher electron density. Smaller size of nitrogen cause higher polarisation of N-H bond than chlorine in Cl-H bond. Final Answer Nitrogen and chlorine both have a nearly similar electronegativity than also only nitrogen forms hydrogen bonding and chlorine doesn’t because -: Small in size compared to chlorine High electron density
