QJEEM03Ch4c5d: JEE Main 2003 Chemistry - Class 11 JEEM03Ch4c5d Solution: In the anion HCOO the two carbon-oxygen bonds are found to be…
In the anion HCOO the two carbon-oxygen bonds are found to be of equal length. What is the reason for it?
Multiple Choice Options
- A The C = O bond is weaker than the C-O bond
- B The anion HCOO- has two resonating structures
- C The anion is obtained by removal of a proton from the acid molecule
- D Electronic orbitals of carbon atom are hybridised
Step-by-Step Verified Solution
The anion is
exists in following resonating structures
And actual structure will be,
Bond order of this anion = = 1.5.
As 1.5 is exactly in the middle of 1 and 2 so, the bond length will be equal between all carbon and oxygen atom.
