(a)
Interpretation:
For the given set of reactions the major products should be determined.
Concept introduction:
Addition Reaction: It is defined as
In addition reaction of
Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation.
Nucleophilic nature depends on the negative charge present in the molecule, the solvent in which it present and the electronegativity of the atom.
If more than one nucleophile present in the reaction then the product of the reaction changed accordingly such that depending on the concentration of the other nucleophile.
(b)
Interpretation:
For the given set of reactions the major products should be determined.
Concept introduction:
Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.
In addition reaction of alkenes when two substituents are placed on same side of
Regioselective reaction: They are reactions which contain more than one product which are actually molecules with same molecular formula but different in the way they are connected and among those products only one product is major.
Markovnikov’s Addition Rule: The unsymmetrical alkene in a chemical compound reacts with hydrogen halide in a way, where halide ions attacks and bond to the more substitution position of carbon-carbon double bond.
Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation.
If more than one nucleophile present in the reaction then the product of the reaction changed accordingly such that depending on the concentration of the other nucleophile.

- In an electrophilic aromatic substitution, the substitution pattern on the product is determine by the directing nature of the substituents on the ring. What controls the substitution pattern in a nucleophilic aromatic substitution reaction?arrow_forwardMatch the conditions most favorable for the substitution reaction type (SN1 or SN2) Strong nucleophile Tertiary carbocation intermediate Protic solvent Primary carbocation intermediatearrow_forwardIn polar process of the reactions Bond formation is unsymmetrical Bond breaking is homolytic O Arrowheads with a "half" head O electrons move from electrophile to nucleophilearrow_forward
- In a Wittig reaction, a ketone or aldehyde reacts as an electrophile with a nucleophile called a Wittig reagent (or phosphonium ylide) to produce an alkene. The Wittig reagent is commonly synthesized first in a two-step process beginning with an alkyl halide, then reacted with the carbonyl compound. In this problem, you'll explore the mechanism of a multi-step synthesis to make an alkene using the Wittig approach.arrow_forwardHow many of the given alkenes will have the same acid-catalyzed hydration and oxymercutation/demercuration?arrow_forwardHow can we determine whether the equilibrium will favor products in a nucleophilic substitution?arrow_forward
- Define Reaction as a Nucleophile ?arrow_forwardWhat is the major product for each of the following reactions? (If an enol is created, write both the enol and keto products. If both ortho and para products are made, write both.)arrow_forwardWhich is/are NOT TRUE about bimolecular nucleophilic substitution reactions? Select one or more: 1. A carbocation intermediate is formed. 2. A strong nucleophile displaces a halogen atom in a concerted mechanism. 3. Presence of polar aprotic solvents promotes this reaction. 4. Methyl halides react faster than secondary alkyl halides.arrow_forward
