Which of the following solvents are polar? (eg have an overall molecular dipole) (hexanes, ethyl acetate, ethanol) ethyl acetate ethyl acetate and ethanol ethanol hexanes ethyl acetate and hexanes

Ethanol

Explanation:

Hello,

Since the hexanes and the ethyl acetate are mostly composed by C-C, C-H and for the ester C-O bonds which are apolar, just the ethanol which has one O-H bond could be classified as polar, allowing H-bridges to be present.

Best regards.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
