how Alcoholic . KOH is useful in reaction

Hey mate !!!
=>There is a vast difference between using the same reagent in two different solvents as in here.
There is a vast difference between using the same reagent in two different solvents as in here.Basically, when we use Alcoholic potassium hydroxide i.e, KOH as a reagent, the negative part of the reagent, that is OH- it acts a a base and abstracts the beta Hydrogen from the saturated substrate( alkyl hallide) present and trasforms it to an alkene in the product, thereby undergoing Elimination reaction...
On the other hand, when we use aqueous potassium hydroxide, i.e, KOH as a reagent, the negative part of the reagent, that is OH- acts a nucleophile and attacks the alpha Carbon atom of the substrate i.e, alkyl hallide, and gives an alcohol as the product, thereby undergoing Substitution reaction..
⚡I hope this make you clear⚡
Answer:
Saponification of amides and esters are two examples when aqueous KOH is preferred (since these are hydrolysis reactions). Alternatively, KOH is used in 'anhydrous' form such as in ethanolic KOH (KOH dissolved in ethanol) when reactions are water sensitive or when performing a dehydration reaction.
