When the positive and negative charge present on carbon ? Give example

Answer»

Solution :If the carbon have three COVALENT bond and ONE vacant orbital then carbon contain (+1) charge e.g. All carbocation `H_(3) overset(+)(C )` means `H - UNDERSET(underset(H)(|))overset(+)(C )-H`
If the carbon have three bond and one non bonding ELECTRON pair then carbon contain (-1) charge. e.g All carbanion `H_(3) bar(C )`: means `H- underset(underset(H)(|))overset(..)( C)-H`
