how can nitrogen form bonds if it is highly electonegative?

Expert Answer:

Electro negativity decreases gradually on descending down the group from N to Bi.

Nitrogen is highly electronegative as compared to phosphorus.

This causes a greater attraction of electrons towards nitrogen in NH3 than towards phosphorus in PH3.

So the extent of hydrogen bonding in PH3 is very less as compared to NH3.

As a result NH3 forms hydrogen bond but PH3 does not.
