Question

if someone who is good at this can help me

1.) What is the bond order of each of the following bonds?

C=N C≡N C—N
Put them in order of increasing bond dissociation energy (BDE).
Is there a connection between bond order and BDE?

2.)Using only the periodic table, select the most electronegative atom in each of the following sets:

As, Se, Br, I
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

Answer:

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)
