What is the role of solvent in nucleophilic substitution reactions?
in sn1 reactions polar solvents are used.why b coz, polar solvent stabilise the intermediate which is formed in the reaction.but in sn2 reactions non polar solvents are used.in this reaction intermediate is not formed.
Is nitrogen a solvent?
No, nitrogen is not a solvent. Nitrogen is a colorless, odorless, and inert gas that is commonly found in the atmosphere. It is not typically used as a solvent in chemical reactions or processes.
Which types of reactions are characterized by two reactants?
Bimolecular reactions involve two reactant molecules coming together to form a new product. This can include reactions such as addition, substitution, and some types of elimination reactions.
What is an acquesious solvent?
An aqueous solvent is a solvent in which water is the primary component. It is commonly used in chemical reactions and processes because of its ability to dissolve a wide variety of substances, including salts, sugars, acids, and gases. Aqueous solvents play a crucial role in biological systems and industrial applications, facilitating reactions and transport of substances. In contrast to organic solvents, which are based on carbon compounds, aqueous solvents provide a unique environment for chemical interactions.
Is skin the primary organ of elimination?
No, skin is not the primary organ of elimination. The primary organs responsible for elimination in the body are the kidneys, which filter waste from the blood and excrete it as urine. The liver also plays a crucial role in detoxifying substances and producing bile for the elimination of certain wastes. While the skin can excrete some waste products through sweat, its role in elimination is secondary compared to the kidneys and liver.
What has the author ERWIN BUNCEL written?

Under which conditions is the elimination reaction highly favoured?
An elimination reaction is highly favoured if: (a) A bulkier base is used (b) A higher temperature is used. (c) the solvent is ethanol rather than water. (d) a stronger base is used.

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.
What is the role of tert-butoxide as a nucleophile in organic chemistry reactions?
Tert-butoxide acts as a strong nucleophile in organic chemistry reactions by donating a pair of electrons to form new chemical bonds with electrophiles, facilitating reactions such as substitution and elimination.
Why alkyl halides undergoSN reactions or elimination reactins in priority?
Alkyl halides undergo both nucleophilic substituions reactions and Elimination reractions depending upon the conditions...In the presence they undergo Elimination Reactions , while in the presence of nucleophile they undergo SN reactions...By: Farman ullah ,Azim kala, masha mansoor, lakki marwat, kpk,Pakistan+92321-9632344
Why does a high temperature favor a nucleophilic elimination over nucleophilic substitution?
A high temperature increases the energy of the system, allowing for more kinetic energy that promotes elimination reactions over substitution reactions. In elimination reactions, the leaving group is expelled with the nucleophile attacking the electrophilic center simultaneously. In contrast, in substitution reactions, the nucleophile replaces the leaving group directly.
What is the role of t-butoxide in organic synthesis reactions?
T-butoxide is a strong base commonly used in organic synthesis reactions to deprotonate acidic hydrogens and facilitate elimination reactions. It helps in forming double bonds and creating new carbon-carbon bonds in organic molecules.
What is the major solvent in the human body?
Water is the major solvent in the human body. It plays a crucial role in various biochemical reactions, transportation of nutrients and waste products, and maintaining body temperature.
What are the key concepts in organic chemistry that differentiate substitution and elimination reactions?
Substitution and elimination reactions are key concepts in organic chemistry that differ in their mechanisms and outcomes. In substitution reactions, one atom or group replaces another in a molecule, while in elimination reactions, a molecule loses atoms or groups to form a new compound. The key difference lies in the way the reactants interact and the products formed. Substitution reactions involve the replacement of one atom or group with another, while elimination reactions involve the removal of atoms or groups to form a double bond or a new compound. Understanding these concepts is crucial in predicting and controlling chemical reactions in organic chemistry.
What are the key differences between the Hofmann and Zaitsev elimination reactions?
The key difference between Hofmann and Zaitsev elimination reactions lies in the regioselectivity of the products formed. In Hofmann elimination, the least substituted alkene is the major product, while in Zaitsev elimination, the most substituted alkene is the major product. This difference is due to the stability of the alkene products formed in each reaction.
What is the role of the solvent in electrolytic solution?
The solvent contain the ions of the solute.
