Question

Inductive effect involves delocalisation of sigma or pie bond?

Answer 1

Inductive effect involves displacement of s electrons .
In a covalent bond between the two dissimilar atoms, the electron pair forming the bond is never shared absolutely equally between the two atoms but is attracted a little more towards the more electronegative atom of the two, eg. The electron pair forming the C–X bond is somewhat more attracted towards the atom X with the result – it attains a partial negative charge while the carbon atoms attain a partial positive charge
