The methyl carbanion CHX3X− has the carbon atom in which hybridisation and shape?
Asp3, regular tetrahedral with four bonds
Bsp3, pyramidal
Csp, linear
Dsp2, trigonal planar
Answer: B
The carbon has three bonding pairs and one lone pair, so four electron domains. This means sp3 hybridisation, and the lone pair makes the shape pyramidal (like NHX3).
