Question

State true or false

Statement: Carbon-oxygen bond length in formic acid are $1.23\mathring{A}$ and $1.36\mathring{A}$ but in sodium formate both the carbon-oxygen bonds have same value, i.e., $1.27\mathring{A}$.

• A. True
• B. False

Answer 1

The correct option is A True

In formic acid the carbon-oxygen bond lengths are different due to hydrogen bonding. But in sodium formate ion the carbon - oxygen bond lengths are equal as it is a resonance hybrid of two equivalent structures.

Hence the correct option is 'A'
