		Al
		Ga
		C
		Si
		N

4 points

Question 3

Which of the following bonds is most polar?

C

Answer 1

1) 5 orbitals are there in 4d subshell

2) Nitrogen(N) requires gretest amount of energy to remove electron because of half filled configuration

3) C-F bond is highly polar because of large electro negetivity difference

4) A and B have different electronegetivity and molecule should be bent shape

5) phosphorous(P) have 5 valency electrons 3S² 3P³

6) Diamagnetic and weekly repelled by magnetic field

7) C=C double bond is stronger than C-C single bond

8)14,15 ionisation energys for core electrons

9) Green light have greatest energy

10) Mn have configuration (Ar)4s²3d⁵

11) P having 3 unpaired electrons

12)N₂ have triple bond between 2 nitrogen atoms

13)4 SP³ hybridied orbitals in oxygen atom

14) Atomic radious radious decreses because effective nuclear charge increases

15) n=6 to n=2 will emits highest energy radiation.

16) Cl is the identity of X

17) Na will decrease its size while changing to product

18) in O-F bond oxygen will have partial positive charge.

19) large cation size and low cation charge

20) SO₂ should exhibit a resonance.

21) two sigma bonds and one pi bond

22) slightly lessthan 109.5

23)XeO₄ will have two pairs of non bonding electrons

24) Al⁺³<F^-<O_2^-2

25) bond order 2 and para magnetic
