Detailed Solution

As the number of +IE [Alkyl groups] groups increases stability of carbcation increases,The delocalisation of α - C–H "σ" bond with empty / positive charge (or) with double bond (or) with free radical is called hyper conjugation.During hyper conjugation no bond bond is observed between carbon and hydrogen and hence hyper conjugation is also said to be "No bond resonance"The group which withdraws the electron from the σ bond of the carbon is called –IE group.carbon in presence of strong base loses proton from ß carbon and forms corresponding alkene.
