Updated On: May 1, 2026
- sp$^2$
- sp$^3$
- sp$^3$d
- sp$^3$d$^2$
- sp$^2$d$^3$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Hybridisation depends on steric number: \[ \text{Steric number} = \text{bond pairs} + \text{lone pairs} \]
Step 1: Structure of CH$_3^-$.
Carbon forms 3 bonds with H and has 1 lone pair. \[ \text{Steric number} = 3 + 1 = 4 \]
Step 2: Hybridisation.
Steric number 4 → sp$^3$
Step 3: Geometry.
Trigonal pyramidal shape.
