- Give the reaction mechanism showing all possible products for the following reactions: (a) Reaction of 1-propene with hydrogen bromide, HBr (9) (b) Reaction of ethene with bromine, Br2 (1)arrow_forwardAmines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.arrow_forwardPredict the major products formed when benzene reacts (just once) with the following reagents.(a) tert-butyl bromide, AlCl3 (b) 1-chlorobutane, AlCl3(c) isobutyl alcohol + BF3 (d) bromine + a nail(e) isobutylene + HF (f) fuming sulfuric acidarrow_forward
- Give 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(c) The E2 elimination of bromoalkane 8 produces a range of alkenes as shown below, answer ALL parts (i) to (iii) Br 8 Ph NaOMe Ph 9 + FOUR more alkenes (i) Identify the structure of the four other possible alkene products. (ii) Assign the stereochemistry (E/Z) for all FIVE alkenes and explain which is likely to be the major product. (iii) With an explanation identify which stereoisomer of 8 would give alkene 9?arrow_forwardCiprofloxacin is a member of the fluoroquinolone class of antibiotics.(a) Which of its rings are aromatic?(b) Which nitrogen atoms are basic?(c) Which protons would you expect to appear between d 6 and d 8 in the proton NMR spectrum?arrow_forward
- (b) Predict the suitable solvent (H2O or CH3COCH3) to increase the reaction of bromopropane (CH3CH2CH2B1) with sodium hydroxide (NaOH). Two reactions are shown below: NaOH, 55 °C CH;CH,CH,Br CH;CH,CH,OH + NaBr H,O (i) NaOH, 55 °C CH;CH,CH,Br CH;CH,CH,OH NaBr H,C CH (ii)arrow_forwardPredict the products of reaction of pent-1-yne with the following reagents.(a) 1 equivalent of HCl (b) 2 equivalents of HCl (c) excess H2, Ni(d) H2, Pd>BaSO4, quinolinearrow_forward(c) Hydrolysis of the haloalkane shown below results in the formation of two alcohols B and C that are stereoisomers of each other. Give the structures of the alcohols B and C and propose a mechanism for their formation ensuring that you explain the stereochemical outcome observed. H3CH2C CH3 H20, heat Br B + Carrow_forward

(a) (b) (d) (f) 5. Propose mechanisms for the following reactions. CH,OH, H+, CH,O OCH3 PhNHNH₂, H+ N–NHPh (a) Ph-C-H Ph—C-H (b) CH3-C-H CH-C-H CH2 CH2-CH₂ Ph3P=CH2 (d) (c) H+ H₂O OH ОН (e) H₂O CHO H NH H (f) OCH3 CH3CH₂NH3 CI OCH3 CH3CH₂NH2 NCH,CH3arrow_forwardPredict the major products of the following reactions.(a) toluene + excess Cl2 (heat, pressure)(b) benzamide (PhCONH2) + Na (liquid NH3, CH3CH2OH)(c) o@xylene + H2 (1000 psi, 100 °C, Rh catalyst)(d) p@xylene + Na (liquid NH3, CH3CH2OH)(e) O2,7-dimethoxynaphthaleneCH3 OCH3 excess LiNH3(l)/THF(CH3)3COHarrow_forward
