1.	Account for the following:The experimentally determined N_F bond length inNF_(3)is greater than the sum of the sigle covalent radii of N andF.
Answer» SOLUTION :This is because both N and F aresmall and hence have high ELECTRON density . So they repal the bond PAIRS thereby making the N-F bond length LARGER.
