The resonance contributors for given species has to be drawn. Concept Introduction: Localized electrons: If the negative charge formed by losing a proton resides only on one atom, they are termed as localized electrons. For example, if an alcohol loses a proton, the electrons remaining will be resides on its single oxygen atom. Delocalized electrons: If the negative charge formed by losing a proton resides on more than two atoms, they are termed as delocalized electrons. For example, if carboxylic acid loses a proton, the electrons remaining will be resides on both oxygen atoms and thus reduces the electron density of the atom making the conjugate base more stable. The above two structures are known as resonance contributors and the actual structure which is called the resonance hybrid will be the composite of the two resonance contributors.

Question

5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn. H3C CH3

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
