When do positive and negative charges appear on a carbon atom? Give examples.
(N/A) If a carbon atom has three covalent bonds and one vacant orbital,it carries a $(+1)$ charge.
Example: All carbocations,such as $H_{3}C^{+}$.
If a carbon atom has three bonds and one non-bonding electron pair,it carries a $(-1)$ charge.
Example: All carbanions,such as $H_{3}C^{-}$.
Example: All carbocations,such as $H_{3}C^{+}$.
