An alcohol A (C4H10) on oxidation with acidified potassium dichromate gives acid B (CHO2Compound A when dehydrated with conc. H,SO, at 443 K gives compound C. Treatment of C witlaqueous H,SO4 gives compound D (C4H10) which is an isomer of A. Compound D is resistanto oxidation but compound A can be easily oxidised. Identify A, B, C and D. Name the type oisomerism exhibited by A and D.
