Which Is More Polar: Methyl Benzoate or Methyl m-Nitrobenzoate?

[Soaring Crane]

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.

That sounds reasonable.
