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-H 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 |
