The hemiacetal reaction is also reversible and can also be catalyzed by either acid or base. Hemiacetals are not usually isolated,except in the formation of 5- and 6-membered rings, as often seen in carbohydrate chemistry.Identify the hemiacetal formed from the intramolecular cyclization of the molecule shown.OHOHNaOH?HCH₂OHOHOHThe hemiacetal product is:HOH₂CHOOHOH₂CHOHOHHOOHHOOHHOOHOHOH₂CОOHOHHHO-OHHOOHCH₂OHOHOH

In case of any doubt please feel free to ask.

Answered: The hemiacetal reaction is also…

Amantadine is effective in preventing infections caused by the influenza A virus and in treating established illnesses. It is thought to block a late stage in the assembly of the virus. Amantadine is synthesized by treating 1-bromoadamantane with acetonitrile in sulfuric acid to give N-adamantylacetamide, which is then converted to amantadine.

A synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.
An alkene is treated with OsO4 followed by H2O2. When the resulting diol is treated with HIO4, the only product obtained is an unsubstituted cyclic ketone with molecular formula C6H10O. What is the structure of the alkene?
A step in a synthesis of PGE1 (prostaglandin E1, alprostadil) is the reaction of a trisubstituted cyclohexene with bromine to form a bromolactone. Propose a mechanism for formation of this bromolactone and account for the observed stereochemistry of each substituent on the cyclohexane ring. Alprostadil is used as a temporary therapy for infants born with congenital heart defects that restrict pulmonary blood flow. It brings about dilation of the ductus arteriosus, which in turn increases blood flow in the lungs and blood oxygenation.
