Question

Zn–C bond polarity in the compounds below

follows the order

• A. I > II > III
• B. III > II > I
• C. II > III > I
• D. II > I > III

Answer 1

The Correct Option is A

• The polarity of the Zn–C bond in these compounds is determined by the electron density around zinc and the bonding environment.
• In compound I, Zn is bonded to a double bond, giving it higher electronegativity and greater polarity.
• In compound II, Zn has a single bond with carbon and is more stable in this form, giving a lower polarity than compound I.
• In compound III, Zn is in a less polar environment (bonded to a single carbon), resulting in the lowest polarity.

Thus, the correct answer is (A).
