In which of the following, the carbon-oxygen bonds are of equal length

1.	In which of the following, the carbon-oxygen bonds are of equal lengths? (1) CH3COO-(2) CH3COOH(3) CH3COOC2H5(4) All of thesepizza no spam.
Answer» EXPLANATION: Acetate ion forms a resonance structure where the negative charge is delocalized over all three atoms and THEREFORE, TWO carbon-oxygen bonds are of equal length. The negative charge is spread over the end of the molecule equally. The two bonds are shorter than a single bond but longer than double bond. Bond length decreases with multiplicity of bond between two atoms. For example, bond length of ethane > ethene > ETHYNE. Hence, assertion is TRUE, reason is true and reason is not the correct explanation for assertion.
