1.5 for the C-O bond. and 1 for the C-H bond.
Bond order of formate ion is 1.5
formate ion
1.5
The formic acid structure is expected to be the most stable, with the resonance structure playing only a small role. In the formate anion, the two resonance structures are equally likely. The steric number is three, the molecule probably trigonal planar about the C. The C-O bonds in the acid are different, with one being a double bond and the other a single bond. Those in the formate ion are basically 1.5 bonds, and we expect the C-O bond in the formate ion to be ≈ 1.3 Å, intermediate between a single and a double bond. 37.
1.33
In a cyanide ion, the bond between the carbon and nitrogen is covalent. I have no idea why you would ask if it is a dative bond, because dative is a grammatical term, not a chemical term.
