Here follows the explanation with proper reasons.
Hence, the remaining F atom is having highest electonegativity among P,V,N,O and F.
So, the order of bond polarity in the order of increasing electro negativity is:
There is a special type of very strong physical bond present known as Hydrogen Bond or rather Hydrogen Bonding present only in three atoms of the entire periodic table, namely, N,O,F due to their very high electro negativity as well as their very small atomic sizes !!
Hope it Helps :)
