Give reason carbon oxygen bond lengths in formic acid are 1.23 Å...
Carbon-oxygen bond lengths in formic acid are 1.23 Å and 1.36 Å, but both the carbon-oxygen bonds in sodium formate have the same value, 1.27 Å. In formic acid the carbon-oxygen bond lengths are different due to hydrogen bonding.

Give reason carbon oxygen bond lengths in formic acid are 1.23 Å...
There are several factors that can influence the bond length between carbon and oxygen in formic acid (HCOOH), which is approximately 1.23 Å (angstroms).
1. Hybridization of the carbon atom: Carbon in formic acid is sp2 hybridized, meaning it forms three sigma bonds with three other atoms (two of them with hydrogen and one with oxygen) and has one lone pair of electrons. The sp2 hybridization allows for a shorter bond length compared to a carbon atom with sp3 hybridization, where the carbon would be bonded to four other atoms.
2. Electronegativity difference: Oxygen is more electronegative than carbon, so it attracts the bonding electrons more strongly. This results in a partial negative charge on the oxygen atom and a partial positive charge on the carbon atom. The greater the electronegativity difference, the shorter the bond length.
3. Resonance structures: Formic acid exists in a resonance hybrid form due to the delocalization of electrons. This means that the double bond character is spread between the carbon-oxygen bond and the carbon-carbon bond. The presence of resonance structures allows for a shorter bond length.
4. Steric effects: The presence of the hydrogen atoms attached to the carbon atom in formic acid can create steric hindrance, which can affect the bond length. However, the steric effects are relatively small in formic acid due to the small size of hydrogen atoms.
Overall, the combination of sp2 hybridization, electronegativity difference, resonance structures, and minimal steric effects contribute to the relatively short bond length between carbon and oxygen in formic acid.
