Concept Introduction : When alkene reacts with water is presence of acid, a hydrocarbon with an alcohol group can be obtained. Alkeneundergoes additionreactionwith
(d)
Interpretation: The synthesis of propanoic acid from an alcohol needs to be explained.
Concept Introduction: The oxidation reaction of alcohols to aldehydes, carboxylic acids and ketones is done by using appropriate oxidizing reagents. Primary alcohols can be oxidized to aldehydes, which can further be oxidized to carboxylic bacids. Secondary alcohols undergo oxidation reaction to form ketone. The oxidation reaction of tertiary alcohols is not possible.

- Q5: Label each chiral carbon in the following molecules as R or S. Make sure the stereocenter to which each of your R/S assignments belong is perfectly clear to the grader. (8pts) R OCH 3 CI H S 2pts for each R/S HO R H !!! I OH CI HN CI R Harrow_forwardCalculate the proton and carbon chemical shifts for this structurearrow_forwardA. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
