Just a recap, if you have on the end a Hydroxyl group, so OH. Are aldehydes and ketones (carbonyls) significantly soluble in water like alcohols and carboxylic acids? As a rule of thumb, the higher the oxidation state of the central carbon, the higher the priority of the functional group. One end is slightly positive one end is slightly negative. The double-bonded oxygen is electronegative, and attracts hydrogens. For instance, R might be an ethyl (CH, Posted 6 years ago. Both the C-N and the N-H bonds are polar due to the electronegativity of the N atom. The question: Is there a method to the naming of these that might help me remember? If the net dipole moment is zero, it is non-polar. Also, keep in mind that ketones H-bond in the same way that aldehydes do: accepting H-bonds. this helped with my studying chem.
