Q4. How is 1-propoxypropane synthesised from propan-1-ol? Write mechanism of this reaction. ANS. 1-propoxypropane can be synthesized from propan-1-ol by dehydration. Propan-1-ol undergoes dehydration in the presence of protic acids (such as H2SO4, H3PO4) to give 1-propoxypropane. The mechanism of this reaction involves the following three steps: Step 1: Protonation Step 2: Nucleophilic attack Step 3: Deprotonation Q5. Write the equation of the reaction of hydrogen iodide with: 1-propoxypropane (ii) Methoxybenzene and (iii) Benzyl ethyl ether ANS. (i) (ii) (iii) 5 MARKS QUESTIONS Q1. Write equations of the following reactions: (i) Friedel-Crafts reaction−alkylation of anisole. (ii) Nitration of anisole. (iii) Bromination of anisole in ethanoic acid medium. (iv) Friedel-Craft‘s acetylation of anisole. (v)Reaction of phenol with Zn dust. Refer Textbook
