The three sequential pericyclic reactions involved in synthesizing coronafacic acid are to be identified. A mechanism for the overall transformation is to be proposed. How the synthesis can be completed is also to be indicated. Concept introduction: In electrocyclic reactions cyclic alkenes or dienes react to yield acyclic conjugated dienes as poducts. A σ bond is broken, a new π bond is formed and some π bonds change their positions. The reactions are reversible. In cycloaddition reactions two unsaturated molecules add to one another to yield a cyclic product. In basic solutions the conjugated enones tautomerize and exist as tautomers. Aldehydes when treated with ammoniacal silver nitrate (Tollens reagent) get oxidized to carboxylic acids.

Question

The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…

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.
