Al, B, C, Si
Ge, As, P, Sn
Li, Rb, Be, Sr

3.)Arrange the bonds in each of the following sets in order of increasing polarity:

C-F, O-F, Be-F
Be-Cl, Br-Cl, C-Cl
C-Cl, C-O, C-H

4.) Draw a Lewis structure for

SiH4
BrF3
H2CO

Answer 1

In question 1, the bond order and bond dissociation energy (BDE) are related. As the bond order increases, the BDE increases. This is because a higher bond order indicates a stronger bond, which requires more energy to break.

Step-by-step explanation:

Question 1:

1. The bond order of the following bonds is:
   - C=N: bond order 2
   - C≡N: bond order 3
   - C—N: bond order 1
   The bond dissociation energy (BDE) increases as the bond order increases.
2. The most electronegative atom in each set is:
   - As, Se, Br, I: I is the most electronegative.
   - Al, B, C, Si: C is the most electronegative.
   - Ge, As, P, Sn: As is the most electronegative.
   - Li, Rb, Be, Sr: Li is the most electronegative.
3. The bonds in each set arranged in order of increasing polarity are:
   - C-F, O-F, Be-F: Be-F < C-F < O-F
   - Be-Cl, Br-Cl, C-Cl: C-Cl < Be-Cl < Br-Cl
   - C-Cl, C-O, C-H: C-H < C-O < C-Cl
4. The Lewis structures for the given molecules are:
   - SiH4: H-Si-H-H
   - BrF3: Br-F-F-F
   - H2CO: H-C=O

Question 2:

1. In question 1, the bond order and bond dissociation energy (BDE) are related. As the bond order increases, the BDE increases. This is because a higher bond order indicates a stronger bond, which requires more energy to break.

Answer 2

1. C—N Bond of 1, C≡N Bond order 3, C=N Bond Order 2

(least BDE) C—N < C=N < C≡N (Most BDE)

2. Br

C

P

Be

3. (least polar) O-F, C-F, Be-F (Most polar)

(Least) Br-Cl, C-Cl, Be-Cl (Most)

(least)C-H, C-Cl, C-O (most)
