Nucleophile is a species that should have
Positive charge
A pair of electrons to donate
Electron deficient species
Electrophiles are electron seeking species. Which of the following is an example for an electrophile.
NH3
H2O
AlCl3
The stability of carbocation follows the order:
Primary> Secondary>Tertiary> Methyl
Secondary>Tertiary> Primary> Methyl
Tertiary > Secondary> Primary > Methyl
Chemical species bearing a negative charge on carbon and possessing eight electrons in its valence shell are called ------------.
Carbocations
Carbanions
Free radicals
Heterolytic fission results in the formation of-
Cations
Anions
Both cations and anions
Nucleophiles donate its pair of electrons to electron deficient species and hence behave as:
Lewis bases
Lewis acids
Bronsted acids
The change in hybridization affects electronegativity of carbon. Arrange C(sp3), C(sp2) and C(sp) in the increasing order of electronegativity.
C(sp3)<C(sp2) <C(sp)
C(sp3)< C(sp) <C(sp2)
C(sp)< C(sp2) <C(sp3)
Carbocations have ------------- shape with positively charged carbon being sp2 hybridised.
Tetrahedral
Trigonal planar
linear
