P overset("Reduction")to Q overset("Dehydration")to R overset("Hydro-chlorination")to S What is P, Q, R, S?

Answer»

`P= CH_(3)COOH"" Q= CH_(3)CH_(2)OH`
`R= CH_(3)CHO"" S= CH_(3)CH_(2)Cl`
`P= CH_(3)CHO"" Q= CH_(3)CH_(2)OH`
`R= CH_(2)= CH_(2)"" S= CH_(3)CH_(2)OH`
`P= CH_(3)COOH"" Q= CH_(3)CH_(2)OH`
`R= CH_(2)= CH_(2)"" S= CH_(3)CH_(2)Cl`
`P= CH_(3)CH_(2)Cl"" Q= CH_(3)CH_(2)OH`
`R= CH_(2)= CH_(2)"" S= CH_(3)CH_(2)Cl`

Solution :`underset("Ethanoic acid")(underset("(P)")(CH_(3)COOH)) underset(LiAlH_(4)H_(2)O)OVERSET("Reduction")to underset("Ethanol")(underset("(Q)")(CH_(3)CH_(2)OH)) overset("Dehydration con" H_(2)SO_(4))underset(473K)to underset("Ethene")(underset("(R)")(CH_(2)=CH_(2))) underset(HCL)overset("Hydrochlorination")to underset("Chloroethane")(underset("(S)")(CH_(3)CH_(2)Cl))`
