Answer :
The orbitals that overlap to form the c-h bond in ethene (h2c=ch2) is s-sp2. The correct option is d.
What are orbitals?
Orbitals are wave functions that are the places where the electrons can be found. There are different orbitals present. These are s, p, d, and f. Orbitals are of different shapes. Round orbital and eight-like shapes.
Each carbon atom is joined to two hydrogen atoms in the ethylene molecule. Therefore, for the C-H sigma bonds in ethylene, overlap two sp2-hybridized orbitals with the 1s orbitals of two hydrogen atoms.
Thus, the correct option is d. s-sp2.
