Which of the following is true for inductive effect?
Inductive effect is a permanent effect.
Inductive effect operates through bonds.
Polarisation of electrons is always in single direction
What do you know about Inductive effect?
The diplacement of an electron (shared) pair along the carbon chain due to the presence of an electron withdrawing or electron releasing groups in the carbon chain is known as inductive effect (I-effect)
but the effect is insignificant beyond third carbon atom.
This effect is transmitted through the chain of σ bonds and diminishes with increasing chain length.
Inductuve effect is thus
(i) A permanent effect
(ii) The electrons never leave their original atomic orbital.
(iii) operates through σ bonds
(iv) Polarization of electron is always in single direction.
(v) It is generally observed in saturated compounds.
(vi) its magnitude (i.e., electron withdrawing or donating power) decreases with increase in distance.
On the basis of inductive effect, groups can be of two types.
When a covalent bond is formed between the atoms of different electronegativities, the e− density is more towards the more EN atom of the bond which results in the formation of a polar covalent bond. Such bond polarity leads to various electronic effects in organic compounds.
For example, in bromopropane, due to more EN of Br than C,C−Br bond is polarised and C-1 acquires (+δ) charge while Br atom gets (−δ) charge.
