- How could you convert each of the following compounds into butanoic acid? Write each step showing all reagents. (a) 1-Butanol (b) 1-Bromobutane (c) 1-Butenearrow_forwardPredict the products of the following acid-base reactions. If the equilibrium would not result in the formation of appreciable amounts of products, you should so indicate. In each case label the stronger acid, the stronger base, the weaker acid, and the weaker base: (a) CH3CH=CH2 + NANH2 (d) CH3C=C: + CH;CH2OH → (e) CH3C=C:- + NH¾CI – | (b) CH;C=CH + NaNH2 (c) CH3CH2CH3 + NANH2 → | HASarrow_forwardElectrophilic aromatic substitution usually occurs at the 1-position of naphthalene, also called the a position. Predict the major products of the reactions of naphthalene with the following reagents.(a) isobutylene and HF (b) cyclohexanol and BF3 (c) fuming sulfuric acidarrow_forward
- How could you convert butanoic acid into the following compounds? Write each step showing the reagents needed. (a) 1-Butanol (b) 1-Bromobutane (c) Pentanoic acid (d) 1-Butene (e) Octanearrow_forwardCompound X (C4H9Br) reacts by heating with NaOH in H2O to form Y. The compound Y then undergoes acid catalysed hydration by H2SO4 in 180°C to form 2-methyl prop-1-ene. (e) Determine the structure of X and Y. (f) Predict a MAJOR product when compound Y reacts with H2SO4 in 140°C. (g) Draw a structural isomer of X. Name the isomer using IUPAC nomenclature. (h) Describe a chemical test to distinguish between compound Y and 1-butanol.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
- Draw line structures of the following compounds and the product you would obtain from the reduction of each.(a) Isopropyl methyl ketone (b) p-Hydroxybenzaldehyde(c) 2-Methylcyclopentanonearrow_forward(a) Why is the following reaction a poor method for the synthesis of t-butyl propyl ether? (b) What would be the major product from this reaction? (c) Propose a better synthesis of r-butyl propyl ether. ÇH, does not give ÇH, CH,CH,CH,-O: *Na + CH,-C-Br > CH,-C-o-CH,CH,CH, CH, CH, t-butyl propyl ether sodium propoxide 1-butyl bromidearrow_forwardDimethyl disulfide, CH,S–SCH3, found in the vaginal secretions of female hamsters, acts as a sexual attractant for the male hamster. Write an equation for its synthesis from methanethiol.arrow_forward
- Predict the products formed when cyclohexanone reacts with the following reagents.(a) CH3NH2, Harrow_forwardPredict the major products formed when benzoyl chloride (PhCOCl) reacts with the following reagents.(a) ethanoarrow_forward(a) How will you convert:(i) Benzene to acetophenone (ii) Propanone to 2-Methylpropan-2-ol(b) Give reasons :(i) Electrophilic substitution in benzoic acid takes place at meta position.(ii) Carboxylic acids are higher boiling liquids than aldehydes, ketones and alcohols of comparable molecular masses.(iii) Propanal is more reactive than propanone in nucleophilic addition reactions.arrow_forward
