Why does aqueous KOH facilitate substitution reaction while alcoholic KOH facilitate elimination reaction?

KOH in Water gives OH- ions which are strong nucleophile and facilitate the substitution reaction while KOH in ethyl alcohol produces C2H5-O- ions which due to larger size observe hindrance when attack on alpha carbon so as a strong base it removes hydrogen from beta carbon and is responsible for elimination reaction.

A dehydration reaction can also be called a?
An "elimination" reaction or "condensation" reaction.
What are the reactants and products of the forward reaction?
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
What is a possible product of a reaction between chloromethane and sodium hydroxide solution?
methanol, substitution reaction
What are nucleophilic reaction?
A reaction in which a negative ion (nucleophile) attacks on a partially positive carbon atom then reaction is known as nucleophilic reaction, it may be substitution reaction or addition reaction.
What is the mechanism for the reaction between bromine and cyclohexane and state the conditions favor the reaction?
electrophilic substitution. and UV light or heat is required to all the reaction to proceed
What is raplacemant reaction in organic chemistry?
There are a few different mechanisms in organic chemistry SN1, SN2, E1, and E2. SN stands for substitution, and E stands for Elimination. The substitution mechanism is where a new bond is formed in place of a preexisting bond. Where as elimination rx is where an atom acts as a leaving group and is not replaced. the numbers denoted the amount of steps that much happen. i.e SN2 is a substitution reaction in which the leaving group first has to leave before the other group attacks the carbocation (if that is the case).
What is Dehydrohalogenation reaction?
basically its an elimination reaction
Why is there low yield in an elimination reaction?
Many times your are removing heavy atoms during an elimination reaction.
What reaction does aromatics undergo?
Substitution
A dehydration reaction can also be called a?
An "elimination" reaction or "condensation" reaction.
Why is an esterification reaction referred to as an elimination reaction?
Because a water molecule is a product of the reaction
Discuss the SN reaction with example?
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
Is esterfication a substitution or addition reaction?
It is substitution because hydrogen of carboxylic acid is replaced by an alkyl group.
What are the reactants and products of the forward reaction?
The reactants are on the left side of the equation, and the products are on the right side of the equation. The reactants are used up in a chemical reaction, and the products are the substances made by the reaction.
What is a possible product of a reaction between chloromethane and sodium hydroxide solution?
methanol, substitution reaction
What is SNi reaction?
The question is probably intended to be about SN1 reaction. See the following from Wikipedia, accessed Feb. 25, 2013: "The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular".
What are nucleophilic reaction?
A reaction in which a negative ion (nucleophile) attacks on a partially positive carbon atom then reaction is known as nucleophilic reaction, it may be substitution reaction or addition reaction.
