- (a) Suggest a synthesis for the following molecules starting with benzene and any other necessary reagents. (i) H2N CI (ii) OH CN 6.arrow_forwardGive 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_forward(a) Write the products of following reactions. Give mechanism with proper stereochemistry? (2 x 2.5 = 5) (ii) Me Δ Δ CNarrow_forward
- Amines 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_forwardGive the major organic product of the following reaction: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
