Question

Which type of hybridization is found in the ethyne molecule?

Answer 1

Hybridization:

• “Hybridization is defined as the process of intermixing of the orbitals of slightly different energies so as to redistribute their energies, resulting in the formation of a new set of orbitals of equivalent energies and shape.”

Hybridization in ethyne

• The ethyne molecule $\left(\mathrm{CH}\equiv \mathrm{CH}\right)$is sp hybridized because it has one sigma and two carbon-carbon pi bonds.

• When one s and one p orbital in the same main shell of an atom combine to generate two new equivalent orbitals, this is known as $\mathrm{sp}$ hybridization. $\mathrm{sp}$ hybridized orbitals are the new orbitals that develop.
• The $2\mathrm{s}$ orbital hybridizes with one of the $2\mathrm{p}$ orbitals to generate two $\mathrm{sp}$ hybridized orbitals for each carbon. These orbitals' frontal lobes face away from each other, producing a straight line.
