(a)
Interpretation: The change in the rate of an E2 reaction is to be stated when the concentration of
Concept introduction: E2 type of reaction follows second order kinetics in which the rate depends on both the reactants. The rate law equation for E2 reaction is expressed as,
(b)
Interpretation: The change in the rate of an E2 reaction is to be stated when the concentration of base is halved.
Concept introduction: E2 type of reaction follows second order kinetics in which the rate depends on both the reactants. The rate law equation for E2 reaction is expressed as,
(c)
Interpretation: The change in the rate of an E2 reaction is to be stated when the solvent is changed from
Concept introduction: E2 reactions are usually preferred in
(d)
Interpretation: The change in the rate of an E2 reaction is to be stated when the leaving is changed from
Concept introduction: A leaving group bigger in size is preferred as it leaves easily and fast while a smaller leaving group leaves with difficulty and slow.
(e)
Interpretation: The change in the rate of an E2 reaction is to be stated when the base is changed from
Concept introduction: Strong base is more efficient in proton abstraction and hence, it is more preferred in E2 type of reactions.
(f)
Interpretation: The change in the rate of an E2 reaction is to be stated when the the alkyl halide is changed from
Concept introduction: The rate of E2 reaction depends on the halide being used. A halide in which carbon attached to the leaving group has more number of alkyl groups is usually preferred.

Draw a reaction mechanism to explain the following reaction. O OH i. OH (aq) LOHarrow_forwardThe behavior of esters and ketones in a reaction with a nucleophile is different because: 1) the carbonyl of the ketone is more positive. 2) the ester cannot form a tetrahedral intermediate. 3) the two oxygens of the ester sterically hinder the nucleophile attack. 4) there is a reasonable leaving group in the ester.

HgSO4/H₂SO4/H₂O B с OH J D Harrow_forwardH Br Br2 CH2Cl2 H, Br Electrophilic addition of bromine, Brɔ, to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH2Clɔ. In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions H Br H- Br H. :Br: Proviouc Noxtarrow_forward10.
