what is the main difference between an sn2 and an sn1 reaction?
235880
The SN2 reaction is concerted. That is, the SN2 occurs in one step, and both the nucleophile and substrate are involved in the rate determining step. Therefore the rate is dependent on both the concentration of substrate and that of the nucleophile. The SN1 reaction proceeds stepwise.

What is the main difference between an exothermic and exergonic reaction? An exothermic reaction is where energy is given off as heat and an exergonic reaction is where energy is given off as light.

Key Takeaway. Nuclear decay reactions occur spontaneously under all conditions and produce more stable daughter nuclei, whereas nuclear transmutation reactions are induced and form a product nucleus that is more massive than the starting material.

It reacts faster in SN1 as alkyl groups are electron donating, therefore the halogen atom is more easily lost and the tertiary carbocation formed is more stable than a secondary carbocation due to the electron pushing effect of the three surrounding alkyl groups, meaning that there is more hyperconjugation and the ...

Synthesis & Decomposition. The two basic reaction types are synthesis and decomposition. Synthesis reactions are reactions that assemble substances together into larger molecules and/or compounds. Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds.

The nucleophiles are almost unsolvated, so it is much easier for them to attack the substrate. Nucleophiles are more nucleophilic in aprotic solvents. So, SN2 reactions "prefer" aprotic solvents.

In an exothermic reaction, the products are at a lower energy than the reactants. The difference between the energy of the reactants and the energy of the products is called the enthalpy change (∆H) of the reaction. ... In an endothermic reaction, the products are at a higher energy than the reactants.

What is the main difference between a double dispacement reaction and an acid-base reaction. Acid and base forms water and salt. An acid-base reaction occurs when an acid and base react. A double displacement reaction occurs when elements in different compounds displaces or exchange places.

N2 is less reactive than O2 in most gaseous reactions because there is a strong triple bond between the atoms, all the valence electrons are in bonding orbitals, and more energy is needed to excite them. ... these electrons are of higher energy and unpaired therefore O2 is more reactive.

Both the reactants are soluble salts. However, when both of them react, sodium ions form ionic bond with nitrate ions while silver ions form bond with carbonate ion, becoming silver carbonate, which is insoluble in aqueous solution.

Th underlying difference between the two is the environment they come from. Sodium nitrate is a naturally occurring chemical compound created during photosynthesis while sodium nitrite is synthetically made. A common substitute for sodium nitrite is celery juice which contains nitrates.

SOCl2 Mechanism For Alcohols To Alkyl Halides: SN2 versus SNi. Most of the time, the reaction of alcohols with thionyl chloride is taught as an SN2 reaction. And indeed, on primary alcohols this is definitely the case.

The key difference between group 1 and group 2 elements is that all group 1 elements have unpaired electrons in their outermost orbital, whereas group 2 elements have paired electrons in their outermost orbital. ... The group 1 and 2 differs from each other depending on the number of electrons in their outermost orbital.

Yes there is a difference. The reaction enthalpy is the heat given off or taken up for the rxn, i.e., the enthalpy difference between the reactants and products. The enthalpy of formation of a compound is the enthalpy change between the elements in their standard state (reactants) and the compound (product).

Answer: The primary functional difference between mitotic anaphase I and meiotic anaphase II is the type and amount of cells at the end result. anaphase I mitosis has two diploid cells. anaphase II meiosis has four haploid cells.

Exothermic reactions have a potential energy difference between the products and reactants that is negative. Endothermic reactions have a potential energy difference between the products and reactants that is positive.

Formal charge of both is zero, but that does not help us to understand chemistry. Above mentioned reaction shows that nitrogen is more negative, and if you do simple QM computation both Mulliken and NBO gives ~-. 44 for N and ~+. 147 for Cl.
