Interpretation:
The compounds A and B formed in the given electrophilic addition reaction are to be identified and the reason is to be explained.
Concept introduction:
>The
The alkene, on reaction with hydrogen bromide in the presence of peroxide, undergoes addition reaction in a way that the hydrogen is bonded to more substituted carbon of double bond and bromine is bonded to less substituted carbon of double bond.Thisis called anti-Markovnikov's rule.

- (i) State reagents G and J. (ii) Draw the structural formula for compounds D, E and H.arrow_forwardNonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardGive reasons for the following: (i) p-nitrophenol is more acidic than p-methylphenol. (ii) Bond length of C—O bond in phenol is shorter than that in methanol. (iii) (CH3)3C—Br on reaction with sodium methoxide (Na+ _OCH3) gives alkene as the main product and not an ether.arrow_forward

Deduce the structure of each compound from the information given. All unknowns in this problem have molecular formula C8H12. (a) Upon catalytic hydrogenation, unknown W gives cyclooctane. Ozonolysis of W, followed by reduction with dimethylsulfide, gives octanedioic acid, HOOC—(CH2)6—COOH. Draw the structure of W. (b) Upon catalytic hydrogenation, unknown X gives cyclooctane. Ozonolysis of X, followed by reduction with dimethyl sulfide, gives two equivalents of butanedial, O=CH—CH2CH2—CH=O. Draw the structure of X.arrow_forwardHydrocarbon X has the formula C6H12.X reacts with one molar equivalent of hydrogen in the presence of a palladium catalyst to form a product having 12 primary hydrogens.Treatment of X with ozone followed by zinc in aqueous acid gives a mixture two aldehydes.What is the structure of X?arrow_forward
