What is the hybridization of C in R - N=C=O

[WACG]

R - N=C=O is the isocyanate group.

I have been trying to use a molsym program and it requires that value as input? The starting value is important. Thanks for any info.

The carbon is sp-hybridized.

Well, thanks for the response but I cannot decide whether you are simply guessing or not. Do you have any reason that supports your response? Thanks

Carbons bound to two atoms and containing no lone pairs are sp hybridized.

Think of your friend carbon dioxide (O=C=O), here's a image of it's space filling model.

Pi bonds are made by sharing the unhybridized p-orbitals. Carbon in this case has two double bonds, containing one pi bond each, while also having two sigma bonds - one with Nitrogen and the other with Oxygen. Therefore, the hybridization is sp with 2 unhybridized p orbitals.
