12. WHY NITROGEN CANNOT EXTEND ITS COORDINATION NUMBER BEYOND 4
114.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.
