SUMMARY

Methyl m-nitrobenzoate is definitively more polar than methyl benzoate due to the presence of the nitro group, which contains highly electronegative nitrogen and oxygen atoms. This increased electronegativity creates a greater dipole moment, enhancing the overall polarity of the molecule. The discussion confirms that the electronegativity difference between the atoms in methyl m-nitrobenzoate contributes significantly to its polar characteristics compared to methyl benzoate.

Homework Statement



I just wanted to check which is more polar: methyl benzoate or methyl m-nitrobenzoate.

Homework Equations



See below.

The Attempt at a Solution



The nitrobenzoate is more polar because it has more electronegative atoms bonded to a carbon, so there is a greater electronegativity difference?

Thanks.
