Why carbonium ion is a nucleophile?

Question

As carbonium ion is positively charged it should be attracted towards negative charge then how it is attracted towards nucleous ( +ve charge) ?

Answer 1

nucleophile doesnt mean that it will attract nucleus. nucleophile is the opposite of electrophile. it forms a chemical bond to its reaction partner (the electrophile) by donating both bonding electrons . Because nucleophiles donate electrons, they are by definition Lewis bases. All molecules or ions with a free pair of electrons can act as nucleophiles, although negative ions (anions) are more potent than neutral reagents. Neutral nucleophilic reactions with solvents such as alcohols and water are named solvolysis.

Answer 2

i'm sorry to say that you arte wrong there. it is not attracted to +ve charged ions. carbonium ion is formed when an extra group is added to its benzene ring structure. it therefore has an extra H atom. this is what causes it to be positive. Benzene undergoes "electrophillic" substitution. so, the H atom releases it self from the benzene ring by "giving" away an electron the the benzene ring. Thus, forming a stable benzene ring. it is the side chain that undergoes further reaction.

the substitution on other groups may influence the reactivity and orientation od the substituted benzene.

Benzene undergoes,
1.electrophillic substitution
e.g Nitration, Sulphonation, Friedel-Crafts reactions

2. Addition reaction
eg. Hydrogenation.

no nucleophillic reactions.

Answer 3

In simple terms, a carbonium ion (carbocation) is not a nucleophile. It does not have the electron pairs to form bonds readily and so it does not.

Answer 4

nucleophile (Nu:) is the electron source. it attacks the molecule. Electrophile (E+) which is an electron sink, and is attacked by the molecule. the nucleus has nothing to do with this. it's heavily shielded and only electrons play in chemical reactions normally
