Interpretation:
The structures of the compounds A and B are to be suggested on the basis of the given observations, and the relationship between them is to be determined.
Concept introduction:
It is a two-step reaction, which takes place with a regioselectivity opposite to the Markovnikov’s rule.
A hydrogen and hydroxyl group are added to the double bonded carbon atoms in a syn manner.
The hydrogen adds to the more substituted carbon atom while the hydroxyl gets attached to a less substituted carbon atom. There are no carbocations formed, and hence no rearrangements take place.
Enantiomers are mirror images. They have opposite configuration at each chiral center.
Diastereomers have the same configuration at one chiral center and opposite configuration at the other chiral center.

- Compound A has molecular formula C4H10, and gives two monochlorides, B and C, on photochemical chlorination. Treatment of either of these monochlorides with potassium tert-butoxide gives the same alkene (C4H8) as the product, but B leads to just one isomer of the alkene, D, where C gives D and another isomer of the alkene, E. Treatment of monochlorides B and C with aqueous ethanol gives products F and G, respectively, both of which are of molecular formula C4H10O. What are the names of compounds A-G?arrow_forwardCompound P (C2H4) which is an alkene undergoes reaction with HCl to produce compound Q (C2H5Cl). Reaction of compound Q with benzene in the presence of AlCl3 as catalyst produces compound R. Then, nitration of compound R in the presence ofnH2SO4 produces two compounds, S and T. But when compound R is reacted with a hot acidified solution of alkaline KMnO4 gives compound U. Deduce the structure of compounds P to U.arrow_forwardOn being heated with a solution of sodium ethoxide in ethanol, compound A (C7H15Br) produced a mixture of two alkenes B and C, each of which had the molecular formula C7H14. Catalytic hydrogenation of major isomer B or minor isomer C gave only 3-ethylpentane. Suggest structures and mechanisms for compounds A, B, and C consistent with these observations.arrow_forward
- An optically active monoterpene (compound A) with molecular formula C10H18O undergoes catalytic hydrogenation to form an optically inactive compound with molecular formula C10H20O (compound B). When compound B is heated with acid, followed by reaction with O3 and then with dimethyl sulfide, one of the products obtained is 4-methylcyclohexanone.

- Compound A, C11H16O, was found to be an optically active alcohol. Despite its apparent unsaturation, no hydrogen was absorbed on catalytic reduction over a Pd/C catalyst. On treatment of A with dilute H2SO4, dehydration occurred and an optically inactive alkene B, C11H14 was produced as the major product. Alkene B, on ozonolysis, gave two products. Product C, C8H8O, was shown to be a methyl ketone while product D, C3H6O, was shown to be an aldehyde.arrow_forward1,2,3,4,5-Pentafluoro-6-nitrobenzene reacts readily with sodium methoxide in methanol at room temperature to yield two major products, each having the molecular formula C7H3F4NO3.
