Polarity

[Ki-nana18]

1. The problem statement, all variables and given/known data
List the solids in order of increasing polarity.
NaCl,C10H8, C6H5COOH, NH2CONH2.

2. Relevant equations
N/A


3. The attempt at a solution

C10H8, C6H5COOH, NH2CONH2, NaCl. My rationale is that the longer the carbon skeleton the least polar.

It really depends on the molecular geometry. You should figure out the structure of the molecule and then calculate the dipole moment by referencing an electronegativity chart for specific numbers. That should get you a good idea of the polarity.
