The total synthesis of the anticholinergic drug, the structure formulas for the intermediates has to be proposed. Concept introduction: Michael reaction: In 1, 4 addition the Nucleophile is added to the carbon β to the carbonyl while the hydrogen is added to the carbon α to the carbonyl. Dieckann Condensation The base-catalyzed intramolecular condensation of a diester. The Dieckmann Condensation works well to produce 5- or 6-membered cyclic β -keto esters, and is usually affected with sodium alkoxide in alcoholic solvent. Sodium borohydride is reducing agent, generally aldehyde and ketone reduced to alcohol.

Question

Caffeine (C8H10N4O2, pictured below) is a weak base. The pKb of caffeine is 10.4. What is the pH of a 0.0155 M solution of caffeine?

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
