Question

Which of the following molecule contain 50% p-character of hybrid orbital in C atom?

Options

• Acetylene

• Methane

• Ethane

• Propane

Answer 1

Acetylene

Explanation:

Because both carbons in the acetylene hybrid orbital are sp-hybridised, the molecule contains 50% p-character of hybrid orbital in the C atom.
One s-orbital and one p-orbital make up an s-orbital, which has 50% s-character and 50% p-character.
