2. WHY NITROGEN CANNOT EXTEND ITS COORDINATION NUMBER BEYOND 4

4.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

5. NH₄NO₃ → PRODUCT ???????????/
(ON HEATING)

for 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

Q.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.
