Question

1-Chlorobutane on reaction with alcoholic potash gives(a) 1-butene (b) 1-butanol(c) 2-butene (d) 2-butanol

Answer 1

2-butanol.lhope this will help you plz mark me as brainliest

Answer 2

Answer:

A) 1 - Butene

Explanation:

The alcoholic KOH converts a single bond to double bond. Whereas with the aqueous KOH , it will not react on the bond, which means that if there is a single bonded carbon on substrate side then the product will only be the single bonded carbon.On reaction with alcoholic KOH, dehydrohalogenation of 1-chlorobutane takes place to form 1-butene. The reaction can be written as:

CH3CH2CH2CH2Cl+KOH ⇒ CH3CH2CH = CH2+KCl+H2O

Thus, 1-Chlorobutane on reaction with alcoholic potash gives 1-butene
