The stability of carbocation follows the order:

Chemical species bearing a negative charge on carbon and possessing eight electrons in its valence shell are called ------------.

The change in hybridization affects electronegativity of carbon. Arrange C(sp3), C(sp2) and C(sp) in the increasing order of electronegativity.

Carbocations have ------------- shape with positively charged carbon being sp2 hybridised.

Carbon has 4 valence electrons. What is the valence configuration?

Electrophiles are electron seeking species. Which of the following is an example for an electrophile.
