Give reasons:
`PbCl_2` is more stable than `PbCl_4`.

Account for the following. (i) 'P b X_2' is more stable than 'P b X_4(X=C l, B r)' (ii) 'PbCl_4' is less stable than 'SnCl_4' but 'PbCl_2' is more stable than 'SnCl_2'

Assertion: 2-Bromobutane on reaction with sodium ethoxide in ethanol gives 1-butene as a majorproduct. Reason : 1-Butene is more stable than 2-butene.

Propene is more stable than ethene due to

Which carbocation is more stable?
