Explanation:
Detailed explanation-1: -The reaction of 2-chlorobutane with aqueous sodium hydroxide gives racemic butan-2-ol, the reaction follows mechanism SNI SNz E2 27.
Detailed explanation-2: -2 chlorobutane +sodium hydroxide = alcohol.
Detailed explanation-3: -Alcoholic KOH is a dehydrating agent and causes dehydrohalogenation in a chemical reaction. When 2 chlorobutane is treated with alcoholic KOH, HCL gas is released with formation of but-2-ene as the major product.
Detailed explanation-4: -The correct option is C 2-Butene.
Detailed explanation-5: -Elimination reactions This is because 2-chlorobutane possesses two different sets of -hydrogens at the first and third carbons respectively, resulting in 1-butene or 2-butene.
