An ylide is a molecule that can be described as a ________.

A) carbanion bound to a negatively charged heteroatom
B) carbocation bound to a positively charged heteroatom
C) carbocation bound to a carbon radical
D) carbocation bound to a diazonium ion
E) carbanion bound to a positively charged heteroatom

Ylide

A compound containing a positively charged atom directly bonded to a negatively charged atom, except oxygen or a halogen.

Carbanion

An ion that contains a negatively charged carbon atom, typically highly reactive in organic chemistry.

Carbocation

A species characterized by a carbon atom bearing a positive charge and three bonds instead of the usual four, making it highly reactive in organic reactions.
