JEE Main 2025 Apr 7 Shift 2, Chemistry Q14: Valence Bond Theory And Hybridisation

JEE Main2025Apr 7, Shift 2Chemistry
Q.

In SO, NO and N the hybridizations at the central atom are respectively :

  1. A

    sp, sp and sp

  2. B

    sp, sp and sp

  3. C

    sp, sp and sp

  4. D

    sp, sp and sp

Solution

In SO, sulfur has one lone pair plus two S=O bonding domains, giving three electron domains around S, so the hybridization is sp with a bent shape.

In NO, nitrogen has one lone pair and two N-O bonding domains, again three electron domains, giving sp hybridization.

In N (azide ion), the central nitrogen is bonded to two other nitrogens through cumulated double bonds with no lone pair contributing to its geometry, giving two electron domains and sp hybridization, consistent with the observed linear shape.
