Concept explainers
Interpretation:
Structures of the principle organic products in each of the given reactions is to be determined.
Concept introduction:
Since
According to Markovnikov’s rule. when an unsymmetrically substituted alkene reacts with a hydrogen halide, hydrogen adds to the carbon that has the greater number of hydrogens and halogen adds to the carbon that has fewer hydrogens.
In hydroboration-oxidation reaction, hydrogen atom gets bonded to the carbon that has fewer hydrogens and the hydroxyl to the carbon that has a greater number of hydrogens. This is a rule opposite of Markovnikov’s addition.

- Lipoic acid is required by many microorganisms for proper growth. As a disulfide, it functions in the living system by catalyzing certain oxidation reactions and is reduced in the process. Write the structure of the reduction product.arrow_forwardThe following reaction has been reported in the chemical literature and gives a single organic product in high yield. Write the structure of the product for the reaction of 2−phenylpropene treated with diborane in tetrahydrofuran followed by oxidation with basic hydrogen peroxide.arrow_forwardProvide the principle organic product for the following reactions. If more than one product is formed indicate which one you expect to be the major product.arrow_forward
- When bromine is added to two beakers, one containing phenyl isopropyl ether and the other containing cyclohexene, the bromine color in both beakers disappears. What observation could you make while performing this test that would allow you to distinguish the alkene from the aryl ether?arrow_forwardAn unknown hydrocarbon Q has a formula C6H12. Q reacts with osmium tetroxide to give a diol R when oxidized with KMnQ4 in an acidic medium Q gives two products. One product is propanoic acid and the other is ketone S. Provide reaction equations to identify the possible structures of Q, R and S.arrow_forward(a) Draw the three isomers of benzenedicarboxylic acid.(b) The isomers have melting points of 210 °C, 343 °C, and 427 °C. Nitration of the isomers at all possible positions was once used to determine their structures. The isomer that melts at 210 °C gives two mononitro isomers. The isomer that melts at 343 °C gives three mononitro isomers. The isomer that melts at 427 °C gives only one mononitro isomer. Show which isomer has which melting point.arrow_forward
- Which of the following is true for the reactions of alkyl halides? (a) The characteristic reactions of alkyl halides are oxidation and reduction.(b) The characteristic reactions of alkyl halides are elimination and substitutionc. The characteristic reactions of alkyl halides are addition and substitutiond. Characteristic reactions of alkyl halides are addition and elimination.arrow_forwardGive the chemical tests to distinguish between following pair of compounds : (i) Propanol and propanone (ii) Ethyl acetate and methyl acetate (iii) Benzaldehyde and benzoic acid (iv) Benzaldehyde and acetaldehyde (v) Formic acid and acetic acid (vi) Propanal and propanol (vii) Ethanoic acid and ethylethanoatearrow_forward(a) Draw the structure of the following :(i) p-Methylbenzaldehyde (ii) 4-Methylpent-3-en-2-one(b) Give chemical tests to distinguish between the following pairs of compounds :(i) Benzoic acid and Ethyl benzoate, (ii) Benzaldehyde and Acetophenone.(iii) Phenol and Benzoic acid.arrow_forward
- 2. Give the structure for the following compounds.arrow_forwardGive reasons for the following :(i) Phenol is more acidic than methanol.(ii) The C—O—H bond angle in alcohols is slightly less than the tetrahedral angle (190°28′).(iii) (CH3)3C—O—CH3 on reaction with HI gives (CH3)3C—I and CH3—OH as the main products and not (CH3)3C—OH and CH3—I.arrow_forward3-Chloro-2-methylpropene reacts with sodium methoxide in methanol to form 3-methoxy-2-methylpropene. For each of the following changes in the reaction conditions, state whether the reaction rate would increase, decrease, or remain the same. Explain your reasoning. In some cases the identity of the major organic product would be expected to change; in such cases, give the expected major product. (a) the same quantities of reagents are dissolved in half the volume of methanol (b) 3-bromo-2-methylpropene is used in place of 3-chloro-2-methylpropene (c) sodium methanethiolate (CH3SNa) is used in place of of sodium methoxidearrow_forward
