12. WHY NITROGEN CANNOT EXTEND ITS COORDINATION NUMBER BEYOND 4

113.WHY NITROGEN CANNOT FORM COMPLEXES BY ACCEPTING ELECTRON PAIRS FROM LIGANDS
14.ON GOING FORM TOP TO BOTTOM IN HYDRIDES FORMED BY 15 GROUP ELEMENTS REDUCING POWER INCREASSES .........SO EASE OF REPLACEMENT OF HYDROGEN INCREASES (OXIDATION)BY Cl .........BUT ACTUALLY IT DECREASES
16. IF A LONE PAIR OCCUPIES S- ORBITAL THEN IT IS LESS EFFECTIVE FOR FORMING A COORDINATE BOND....WHY????????????
1for 2 and 3
nitrogen does not have d-0rbitals so cannot extend its coordination number
absence of d-orbitals does not allow nitrogen to accept lp
1Q.4) what do u mean by' SO EASE OF REPLACEMENT OF HYDROGEN INCREASES (OXIDATION)BY Cl .........BUT ACTUALLY IT DECREASES'.
Q.5)on heating NH4NO3 , it gives N2O and H2O
Q.6) s-orbital electrons r closest to nucleus. thus,when an electron pair enters s-orbital , then it becomes too difficult to be donated then.
