2. Acetone consists of three carbon, six hydrogens and one oxygen atom
3. And H2O donates the hydrogens and the electrons with it.
4. In water, the oxygen acts negative and the hydrogens act positive.
5. Because it's no joke to actually strip away electrons and hydrogens from an actual water molecule.
6. Alkanes are the simplest and least reactive hydrocarbon species containing only carbons and hydrogens
7. 6¿ are hydrogens or C¿1?-C¿4?-alkyl groups, or one of the radicals R?
8. Acetanilide is a derivative of aniline, where one of the hydrogens on the nitrogen atom has been replaced with an acetyl group
9. So, the oxygen in water behaves as though it's negative, and the hydrogens behave as though they're positive.
10. Alkyl Cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula
