Question

What is the angle between the carbon-oxygen bond and one of the carbon-fluorine bonds in the carbonyl fluoride ( cof2 ) molecule?

Answer 1

Answer: More than $120^o$.

Explanation:

In carbonyl fluoride molecule, carbon is $sp^2$ hybridized with planar geometry. Oxygen in doubled bonded to the carbon and two fluorine atoms are single bonded with carbon atom.

In $sp^2$ hybridization the angle between the two adjacent hybridized molecular orbitals is at $120^o$.Since, lone pair present on the oxygen atoms will repel the carbon-fluorine bond pairs away by which angle between (O-C-F) will become more than $120^o$.

Answer 2

It has a trigonal planar structure. So, the calculated angle is 127.3 degrees.
You can see the structure in the picture.
