Which is the correct hybridization state and geometry for the carbon atom in hcn?

a. sp, linear
b. sp^2, trigonal planar
c. sp3, tetrahedral
d. none of the above

a. sp, linear

Explanation:

The bonds in the hydrogen cyanide molecule are a simple bond from the C to the H and a triple bond between the N and the C, as can be seen in the figure.

This means that the carbon atom in this molecule has an sp hybridization and a linear geometry as a result of the 2 pi bonds with the nitrogen atom.
