The following molecule belongs to a class of compounds known as allenes.Based on your knowledge of bonding,predict the hybridization of the carbon atom indicated by the arrow.

Question

Quizplus · Accepted Answer

Allene consists of two double bonds between three consecutive carbon atoms. The carbon atom indicated by the arrow has two double bonds and no lone pairs, which means it will have a linear geometry. The linear geometry requires two unhybridized p orbitals in addition to two sp hybrid orbitals. Since the carbon atom only has two hybrid orbitals, it must have an sp hybridization.
