The bond pair involved in hydrogen bonding was attracted more towards higly electronegative atom, as a result h atom will start acquiring a partial positive charge(δ +) & the electronegative atom will acquire a partial negative charge(δ-.
In addition to the four major bond types described above, there is an interaction called hydrogen bonding this takes place when a hydrogen atom, bonded to an electronegative atom such as oxygen, fluorine, or nitrogen, is also attracted to the negative end of.
Nitrogen is highly electronegative as compared to phosphorus this causes a greater attraction of electrons towards nitrogen in nh 3 than towards phosphorus in ph 3hence, the extent of hydrogen bonding in ph 3 is very less as compared to nh 3.
