Lucas test and oxidation of drawn alcohols

14 questions on Lucas test and oxidation of drawn alcohols from the Alcohols, Phenols and Ethers chapter: 3 NEET level, 6 JEE Main, 5 JEE Advanced. Each one opens with its answer and solution.

• Lucas reagent (concentrated HCl with anhydrous ZnCl2) is added to the alcohol shown at room temperature. What is observed? NEET level, drawn structure
• The alcohol shown is oxidised with pyridinium chlorochromate (PCC) in dichloromethane. Which structure is the product? NEET level, drawn structure
• The vapour of the alcohol shown is passed over copper at 573 K. Which structure is the main organic product? NEET level, drawn structure
• Lucas reagent is added to the alcohol shown at room temperature. Assume that the rate is governed by S_N1 carbocation formation. What is observed? JEE Main level, drawn structure
• The alcohol shown becomes turbid with Lucas reagent at room temperature after about 5 minutes. Which isomer of molecular formula C4H10O among the structures sho... JEE Main level, drawn structure
