ISOPROPYL CYCLOHEXANE may be incompatible with strong oxidizing agents like nitric acid. The substituent isopropyl has distinct "Y" shape, and the propyl substituent is just a jagged line of CH 2 CH 2 CH 3.
One alkyl group has three carbon atoms and is attached by the middle carbon atom; it is an isopropyl group. (See chemical bonding for a discussion of hybrid orbitals.) Or if want to do the systematic naming we could call this five, comma, six, di, diethyl. So we could say five, six diethyl, five, five isopropyl. .

Thus the isopropyl group has higher priority (circled in B). Numbering . These molecules show a solvatochromism effect in solution and electrical conductivity in the solid state in their neutral form. This compound has the carbonyl group between two alkyl groups, so it is a ketone. Answer (1 of 5): We need to know a few more things before knowing about isopropyl group.
