Question

What types of hybridisation are involved with the central atom of a molecule having following shapes: (i) planar (ii) a regular tetrahedral (iii) an equilateral triangle

Answer 1

Planar molecule = $\sf{sp}$ hybridisation

Tetrahedral = $\sf{sp^3}$ hybridisation

Trigonal planar = $\sf{sp^2}$ hybridisation

Answer 2

Planar molecule = \sf{sp}sp hybridisation

Tetrahedral = \sf{sp^3}sp

3

hybridisation

Trigonal planar = \sf{sp^2}sp

2

hybridisation
