JEE Advanced Chemistry Question (2022) — Solution
Options
- A. σ orbital has a total of two nodal planes.
- B. σ * orbital has one node in the xz -plane containing the molecular axis.
- C. π orbital has one node in the plane which is perpendicular to the molecular axis and goes through the center of the molecule
- D. π * orbital has one node in the xy -plane containing the molecular axis.
Answer
D. π * orbital has one node in the xy -plane containing the molecular axis.
Step-by-step solution
When this orbital combine along the internuclear axis then σ orbital is formed while this orbital approach each other parallel to each other and perpendicular to the internuclear axis π orbital is formed.
