Q.
Match the following columns and choose the correct option from the codes given below.
Column I(Representation)
Column II(Type)
A

1
Positive overlap
B

2
Zero overlap
C

3
Negative overlap
| Column I(Representation) | Column II(Type) | ||
|---|---|---|---|
| A | ![]() |
1 | Positive overlap |
| B | ![]() |
2 | Zero overlap |
| C | ![]() |
3 | Negative overlap |
Chemical Bonding and Molecular Structure
Solution:
The correct match is $A \rightarrow 2, B \rightarrow 3, C \rightarrow 1$
A

Zero overlap (Out of phase due to different orientation or direction of approach)
B

Negative overlap (Orbitals forming bond have different sign and orientation)
C

Positive overlap (Orbitals forming bond have same sign and orientation in space)
