1) Which of the following reactions is used to prepare isobutane? A) Wurtz reaction of $C_{2}H_{5} Br$ B) Hydrolysis of n-butylmagnesium iodide C) Reduction of propanol with red phosphorus and HI D) Decarboxylation of 3-methylbutanoic acid Answer: Option DExplanation:3-methylbutanoic acid gives isobutane on decarboxylation i.e, While Wurtz reaction of C2H5 Br gives, n-butane and hydrolysis of n-butyl magnesium bromide gives n-butane but reduction of propanol with HI/P gives propane
