For the Lewis structure of the cyanamide ion that contains two double bonds, N=C=NH^-,The hybrid orbitals used by the underlined nitrogen atom and the carbon atom,Respectively,Are A) sp² and sp³. B) sp and sp. C) sp² and sp². D) sp and sp³. E) sp² and sp.

Question

Quizplus · Accepted Answer

The underlined nitrogen atom has 3 atoms and 1 lone pair, which leads to the hybridization of sp2. 
The carbon atom has 2 atoms and 2 double bonds, leading to the hybridization of sp. 
Therefore, the hybrid orbitals used by the underlined nitrogen atom and the carbon atom, respectively, are sp2 and sp.
