Question

The hybridisation scheme for the central atom includes a d-orbital contribution in

Answer 1

The molecule of benzene ($ \text{C}_6\text{H}_6 $) consists of six carbon atoms arranged in a hexagonal ring. Each carbon atom in benzene is $ sp^2 $-hybridized. Let's break down how many $ sp^2 $ hybrid orbitals are present in benzene:

Each carbon atom in the benzene molecule is $ sp^2 $-hybridized. This means that one 2s orbital and two 2p orbitals of each carbon atom combine to form three $ sp^2 $ hybrid orbitals.
Since benzene has six carbon atoms, and each carbon atom contributes three $ sp^2 $ hybrid orbitals, the total number of $ sp^2 $ hybrid orbitals is calculated as follows:

Total number of $ sp^2 $ hybrid orbitals = Number of carbon atoms × $ sp^2 $ hybrid orbitals per carbon atom

Total number of $ sp^2 $ hybrid orbitals = $ 6 \times 3 = 18 $

Thus, the number of $ sp^2 $ hybrid orbitals in a benzene molecule is 18. Therefore, the correct answer is 18.
