Can you help me to propose a structure for this NMR?

When the 1HNMR spectrum of an alcohol is run in dimethylsulfoxide (DMSO) solvent rather than in chloroform, exchange of the Ο-H proton is slow and spin-spin splitting is seen between the Ο-H proton and C-H protons on the adjacent carbon. What spin multiplicities would you expect for the hydroxyl protons in the following alcohols? (a) 2-Methyl-2-propanol (b) Cyclohexanol (c) Ethanol (d) 2-Propanol (e) Cholesterol (f) 1-Methylcyclohexanol

How could you use 1H and 13C NMR to help distinguish the following isomeric compounds of the formula C4H8?
