What is the relationship between the following compounds? tautomers enantiomers diastereomers identical The type of reaction in the following reaction is S_N 1 reaction S_N2 reaction E1cB reaction E1 reaction E2 reaction Which of the following is Grignard reagent? R-Mg-X (R)_2CuLi CH_2I_2/Zn(Cu) none of the above The transformation is an oxidation a reduction neither an oxidation nor reduction cannot be determined How do you describe the following reaction? S_N^1 reaction S_N^2 reaction Inversion of configuration both B and CExplanation / Answer
6) it is tautomeric.
It is related to keto-enol tautomerism where there is chemical equilibrium between ketone form and enol ( alcohol) form of molecule.
7) it is E1cb reaction.
The E1cB reaction a type ofelimination reaction which occurs under basic conditions, where a particularly poor leaving group (such as -OH or -OR) and an acidic hydrogen eliminate to form an additional bond. E1cB is a two-step process. First, abase abstracts the most acidic proton to generate a stabilized anion. The lone pair of electrons on the anion then moves to the neighboring atom, thus expelling the leaving group and forming double or triple bond.
8) R-Mg-X is grignard reagent.
_9) it is reduction.
In Reductive dehalogenation reaction makes carbon atom gains electron by hydrogen atom.
10) SN2 reaction.
All SN2 reaction occurs with backside attack which causes inversion of configuration.
Frontside Attack: In a frontside attack, the nucleophile attacks the electrophilic center on the same side as the leaving group. When a frontside attack occurs, the stereochemistry of the product remains the same; that is, we have retention of configuration. Backside Attack: In a backside attack, the nucleophile attacks the electrophilic center on the side that is opposite to the leaving group. When a backside attack occurs, the stereochemistry of the product does not stay the same. There is inversion of configuration.
