Column I

Column II

Explanation

A. Carbocation

sp2 hybridised carbon with empty p-orbital

H3C+ is carbocation. Loss of e- makes it's p-orbitals empty

(sp2-hybridised carbon)

B. Nucleophile

Species that can supply a pair of electrons.

Nucleus loving i.e., having negative charge or excess of electrons

C. Hyperconjugation

Conjugation of electrons of C-Hσ bond with empty p-orbital present at adjacent positively charged carbon

D. Electrophile

Species that can receive a pair of electrons

Electron loving i.e., positive charge or lack of electrons
