Why alkyl halides give alcohol with aqueous KOH whereas wit alcoholic KOH they give alkenes?
Alkyl halides undergo an E2 elimination reaction with alcoholic KOH to form alkenes due to the basicity of KOH in an alcohol solvent. However, with aqueous KOH, alkyl halides undergo an SN2 substitution reaction to form alcohols. The solvents play a significant role in determining the type of reaction that occurs.

Why aqueous potassium hydroxide leads to the formation of alcohols but alcoholic potassium hydroxide leads to the formation of hydrocarbon?
Aqueous potassium hydroxide can act as a nucleophile, attacking the electrophilic carbon in an alkyl halide to form an alcohol via an SN2 reaction. On the other hand, alcoholic potassium hydroxide serves as a strong base, favoring elimination reactions like E2, which lead to the formation of alkenes or alkynes from alkyl halides.
What will react with alcoholic silver nitrate?
Alcoholic silver nitrate reacts with alkyl halides to form silver halide and alkyl nitrate compounds. This reaction is commonly used in organic chemistry to identify the presence of alkyl halides in a sample.
Why alkyl halides undergo elimination reaction?
Alkyl halides undergo elimination reactions, such as E2 and E1, to form alkenes and hydrogen halides. This occurs in the presence of a base or nucleophile due to the tendency of the halide to leave, resulting in the formation of a double bond. The presence of a strong base favors elimination over substitution reactions.
What are the key characteristics and reactivity of vinyl alkyl halides in organic chemistry reactions?
Vinyl alkyl halides are compounds with a double bond between a carbon atom and a halogen atom. They are typically more reactive than alkyl halides due to the presence of the double bond. In reactions, vinyl alkyl halides can undergo addition reactions to the double bond, leading to the formation of new carbon-carbon bonds. Additionally, they can participate in elimination reactions to form alkenes. Overall, the key characteristics of vinyl alkyl halides include their reactivity towards addition and elimination reactions in organic chemistry.
What are the properties and reactivity of pseudo halides in comparison to traditional halides?
Pseudo halides have similar properties and reactivity to traditional halides, but they are not true halides. They can act as halogens in chemical reactions, but they may have different characteristics due to their structure. Overall, pseudo halides exhibit some similarities and differences compared to traditional halides.

Why alcoholic medium in reaction KCN and alkyl halide?
Alcohol is often used as a reaction medium for reactions between KCN and alkyl halides because alcohol can dissolve both compounds, allowing for efficient mixing and interaction between the reactants. Additionally, alcohols can act as nucleophiles, which can facilitate the nucleophilic substitution reaction between KCN and alkyl halides to form nitriles.
What will react with alcoholic silver nitrate?
Alcoholic silver nitrate reacts with alkyl halides to form silver halide and alkyl nitrate compounds. This reaction is commonly used in organic chemistry to identify the presence of alkyl halides in a sample.
What is the importance of alkenes?
Alkenes are very important as: 1. They are used in the manufacture of polythene, Mustard gas(beta-beta dichloro ethyl sulphide) 2. Ethene, one of the alkenes, is used as a general anaesthetic and for artificial ripening of fruits. 3. Alkenes are used as a starting material for a large number of chemicals of industrial use such as glycols(antifreeze) , ethyl halide and ethyl alcohol.

What is unsymmetrical addition reaction?
Unsymmetrical addition reaction is a chemical reaction in which two different reactants add to an unsymmetrical molecule, resulting in the formation of a new molecule with different substituents at the reacting sites. This type of reaction typically occurs with alkenes or alkynes and can lead to the formation of stereoisomers when chiral compounds are involved. Examples include the addition of hydrogen halides to alkenes or the addition of nucleophiles to carbonyl compounds.
Are halides electron withdrawing or donating?
Halides are electron-withdrawing.
Does halides contain silicon?
Yes, halides can contain silicon. Silicon can form halides by combining with elements such as fluorine, chlorine, bromine, and iodine to create silicon halides. Examples of silicon halides include silicon tetrafluoride (SiF4) and silicon tetrachloride (SiCl4).
Is silver halides a metal or alloy?
Siver Halides are neither a metal or an alloy. They are a salt.
