Answer
The hybridization state for the central carbon in this molecule is $sp$.
Work Step by Step
1. Find the number of bonded atoms.
- There is 2 oxygens : 2 atoms.
2. Find the number of lone pairs.
- The central carbon doesn't have lone pairs.
3. The hybridization state number will be the sum of these numbers minus 1.
2 + 0 = 2
2 - 1 = 1
- Therefore, the hybridization state is $sp^1 = sp$
