Observe the following sequence of reactions and select the option(s) that is/are true in this context.
  • a)
    The reagent 'P' is cold alkaline solution of KMnO4.
  • b)
    The reagent 'P' is hot and acidic solution of KMnO4.
  • c)
    The reagent 'Q' is an oxidising agent.
  • d)
    The reagent 'S' is a mixture of NaOH and CaO.
Correct answer is option 'B,C'. Can you explain this answer?
Most Upvoted Answer
Observe the following sequence of reactions and select the option(s) ...
Option (a) is incorrect as cold alkaline solution of KMnO4 would produce vicinal diols.
Option (b) is correct as KMnO4 is stronger oxidising agent and in the acidic medium, it oxidises the alkene by breaking the carbon-carbon double bond and replacing it with two carbon-oxygen double bonds.
Option (c) is correct as the process is ozonolysis by ozone, which is arrested at the aldehyde stage by adding zinc water.
Option (d) is incorrect as decarboxylation, with soda lime, would produce ethane. Ethene is obtained by Kolbe's electrolysis. Hence, 'S' represents the process of electrolysis and not a reagent.
