Question

Which of the following statements related to S N1 reactions is not true? - The heterolysis of a bond between atoms which do not bear formal charges always produces a cation and an anion - The charged carbon atom of a carbocation has a complete octet of valence shell electrons - Carbocations are Lewis acids - Nucleophiles seek centers of low electron density

Answer 1

Answer:

The charged carbon atom of a carbocation has a complete octet of valence shell electrons

Explanation:

A charged carbon atom of a carbocation has a valence shell that is not filled, that's why it acts as an electrophile (or a Lewis base). This unfilled valence shell is also the reason of the nucleophilic attack that takes place during the second step of a SN1 reaction.
