Williamson synthesis and HI cleavage of drawn ethers

13 questions on Williamson synthesis and HI cleavage of drawn ethers from the Alcohols, Phenols and Ethers chapter: 2 NEET level, 5 JEE Main, 6 JEE Advanced. Each one opens with its answer and solution.

• Which pair of reactants is best for preparing the ether shown by the Williamson synthesis? NEET level, drawn structure
• The ether shown is heated with excess concentrated HI. Which structure is the organic product that still contains the benzene ring? NEET level, drawn structure
• The ether shown is treated with one equivalent of HI. Iodide attacks the less hindered carbon of the protonated ether by S_N2. Which structure is the alkyl iodi... JEE Main level, drawn structure
• The ether shown reacts with cold HI. Because one alkyl group can form a stable carbocation, the cleavage goes by the S_N1 route. Which structure is the alkyl io... JEE Main level, drawn structure
• The ether shown is to be made by a Williamson-type reaction in good yield. Which statement is correct? JEE Main level, drawn structure
• Which reactant, on treatment with aqueous sodium hydroxide, gives the cyclic ether shown by an intramolecular Williamson reaction? JEE Main level, drawn structure
• Which pair of reactants is best for preparing the ether shown by the Williamson synthesis, so that elimination is minimised? JEE Main level, drawn structure
• The ether shown is heated with excess concentrated HI until every cleavable carbon-oxygen bond is broken. Assume that each bond from oxygen to an sp3 carbon con... JEE Advanced level, drawn structure
• The ether shown reacts with one equivalent of HI. By convention, a methyl alkyl ether is cleaved by S_N2 attack of iodide at the methyl carbon. Choose all corre... JEE Advanced level, drawn structure
• Choose all correct statements about the ether shown. JEE Advanced level, drawn structure
• The ether shown is treated with one equivalent of HI and the resulting alkyl iodide is isolated and heated with alcoholic KOH. Which structure is the major alke... JEE Advanced level, drawn structure
• The compound shown is brominated with Br2 and FeBr3 (the methoxy group is the stronger director), and the product is then heated with excess concentrated HI. Wh... JEE Advanced level, drawn structure
• The aryl halide shown cannot take part as the halide in a Williamson synthesis. Which of the ethers shown can NOT be made in good yield from any alkoxide and an... JEE Advanced level, drawn structure
