What is the Major Product of the Following Reaction?
The main product of the reaction is an alkene in the form of a bulky hindered base. The reaction favors elimination over substitution. Thus, option (A) is correct. In addition, what is the name of the main product? Here’s a brief explanation. The reaction takes place in the presence of a basic compound, an alkene, and a p-phenyl group on the aniline.
Alkene
The electrophilic addition of HX to alkenes gives the major product, alcohol, and produces two constitutional isomers: haloalkane and alkene. This reaction is defined by the dominant constitutional isomer. The regioselectivity trend is summarized by Russian chemist Vladimir Markovnikov. During this reaction, a hydrogen atom is added to the double bond carbon with more hydrogen atoms.
The carbon-carbon double bond in an alkene acts as the nucleophile, attracting the partially positively charged hydrogen in HBr. The alkenes’ p electrons move toward hydrogen while the X-Y bonding electrons move away. In this way, a new s bond is formed between the double bonds of the carbon and hydrogen. This reaction is known as reforming and involves the use of triethylaluminium.
Phenyl group of aniline
Aniline is an aromatic molecule with the same chemical structure as benzene. Its electron density is higher than that of benzene, which makes it participate in more electrophilic aromatic substitution reactions. Despite its high reactivity, aniline has a number of undesirable properties, which make it highly susceptible to oxidation and a variety of impurities. Freshly purified aniline is colorless, but as impurities accumulate, it gradually turns yellow or red. It can also be diazotized to form the diazonium salt, which undergoes nucleophilic substitution reactions. As a result, diazotized aniline is a base and a nucleophile, whereas the original aniline is a nucleophile.
The acetylation of an unknown amine produces p-ethylaniline, a primary amine with an ethyl group located in the paraposition of the amino group. This reaction produces 2-amino-3-methylpentane, which has a methyl group at the third carbon atom and an amino group at the second carbon atom. The reaction proceeds in the reverse order for the production of acetanilide, a secondary amine.

Diol
In the following reaction, benzylic and cyclic diols are subjected to oxidative conditions. These conditions resulted in good to excellent selectivity and conversion. The catalyst was prepared in situ from Mn(ClO4)2*6H2O and PCA, and the base (NaOAc) was added to acetonitrile. The resulting mixtures were mixed to form a stoichrometric catalyst.
The substitution of a cyclohexadiene ring with a hydroxyl group yields vicinal diols, which have two hydroxyl groups attached to adjacent atoms. Examples of vicinal diols include 1,2-ethanediol and ethylene glycol, which are commonly used in the antifreeze industry. Other common vicinal diols are alpha propylene glycol and propane-1,2-diol.
Nitrate
This chemical reaction produces a nitrogen compound. It is reversible and proceeds through a process known as cyclic bromination. The major product of the reaction is nitrate. Nitrate is used in the production of paint and is used to disinfect surfaces. Nitrate is a naturally occurring element in the human body. It is produced in large quantities in our environment. The following reaction is a good example of this chemical reaction.
The endo-isomer is ionized to the classical 2o-carbocation, which is then rapidly transformed into a nonclassical ion. The acyl nitrene moiety is left with a meta to nitro function. Nitrate is a widely used chemical. The reaction of nitrite with nitric acid generates the following major products:
PCC
The oxidation of cyclohexyl derivatives proceeds at a faster rate with cis-4-t-butyl cyclohexyl bromide than with trans-4-t-butyl cyanohexane. The rate of the reaction is determined by the steric effects of the two isomers. The axial conformer of cyclohexyl bromide undergoes the most rapid reaction.
A cyclohexane is the product of the reaction with PCC. It can also be used as an alternative to a solvent. PCC is a milder oxidant compared to chromic acid, but is not as effective in oxidizing primary alcohols. In this reaction, chromic acid oxidizes a primary alcohol to a carboxylic acid, while PCC oxidizes it to an aldehyde. The primary alcohol in 1-pentane will be converted to the aldehyde pentanal.
