Column I

Column II

Explanation

A. Free radical

Trigonal planar

Free radicals are formed by homolytic fission e.g., CoH3 hybridization sp2

B. Carbocation

Trigonal planar

Formed by heterolytic fission when carbon is attached to a more electronegative atom e.g., C+H3 hybridization sp2

C. Carbanion

Pyramidal

Formed by heterolytic fission when carbon is attached to more  electropositive atom e.g., CH3- hybridization sp3


Hint: Free radicals are formed by homolytic fission e.g., \(\stackrel{\circ}{\mathrm{C}} \mathrm{H}_3\) hybridization sp2.
