How do you determine if a molecule is polar or nonpolar? Its my understanding that an alcohol will have greater polarity than a similar ketone or aldehyde for one and only one reason: ANSWER: the alcohol has a greater net dipole moment than the carbonyl. Which functional groups have the highest priority? Group can participate in specific chemical reactions accept Lys at P1, and polarity reactivity. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Both the C-N and the N-H bonds are polar due to the electronegativity of the N atom.
