Hybridization and Coplanarity in Molecules

The video tutorial explains the concept of coplanarity in molecules, focusing on the hybridization states that allow atoms to be in the same plane. It covers sp, sp2, and sp3 hybridization, providing examples of planar molecules like benzene and alkene, and non-planar molecules like cyclohexane. The tutorial concludes with a detailed analysis of various molecules and identifies which are coplanar, ultimately determining that option A is the correct answer.

What does the term 'coplanar' mean in the context of molecular structures?

• All atoms are in different planes.

• All atoms are in one plane.

• Atoms are in a linear arrangement.
