Question

An alcohol a c4h10o on oxidation with acidified potassium dichromate gives acid bb c4h8o2 compound a when dehydrated with conc h2so4 at 443k gives compd c treatment of c with aqueous h2so4 gives compd d c4h100 which is an isomer of a compound d is resistant to oxidation but compound a can be easily oxidised .Identify a b c d

Answer 1

Hi, here is your question

An alcohol a C4H10O on oxidation with acidified potassium dichromate gives acid bb c4h8o2 compound a when dehydrated with conc h2so4 at 443k gives compd c treatment of c with aqueous h2so4 gives compd d c4h100 which is an isomer of a compound d is resistant to oxidation but compound a can be easily oxidised .

So alcohol A is CH₃CH₂CH₂CH₂OH

Acid B is CH₃CH₂CH₂COOH

But this dehydration with H2SO4 is normally giving acid anhydride
