Question

For the molecule allene, \({{\rm{H}}_{\rm{2}}}{\rm{C = C = C}}{{\rm{H}}_{\rm{2}}}\) , give the hybridization of each carbon atom. Will the hydrogen atoms be in the same plane or perpendicular planes?

Short answer

Two \({\rm{\pi }}\) bonds bind the core carbon atom. \({\rm{\pi }}\) bonding requires perpendicular \({\rm{p}}\) orbitals. As a result, the \({\rm{C}}{{\rm{H}}_{\rm{2}}}\) planes must be perpendicular to one another, and the hydrogen atoms must be in those planes.

Step-by-step solution

Define molecule

A molecule is the smallest unit of a substance that holds the compound's chemical characteristics. Molecules are made up of atoms arranged in groups.

Explanation

Two \({\rm{\pi }}\) bonds connect the core carbon atom. In \({\rm{\pi }}\) bonding, the \({\rm{p}}\) orbitals must be perpendicular to each other. As a result, the \({\rm{C}}{{\rm{H}}_{\rm{2}}}\) planes must be perpendicular to one another, and the hydrogen atoms will be in those planes.
