Question

Which one of the following is incorrect regarding Inductive effect ?

• A. Involves polarisation of pi electron
• B. Distance independent effect
• C. Creates net negative charge in the molecule
• D. All of the above

Answer 1

The correct option is D All of the above

1. Permanent polarisation of bond due to shifting of shared pair of sigma electrons towards the more electronegative atom/substituent.
2. Inductive effect leads to development of ẟ- or ẟ+ on the carbon atom sharing a bond with the substituent. The fractional electronic charges on the two atoms in a polar covalent bond are called partial charges and are denoted by ẟ+/ẟ- (delta).
3. As distance increases, strength of Inductive effect decreases.
4. Inductive effect ceases to operate (or negligible) after 3rd Carbon from the substituent hence, it is distance dependent.
