What is stereospecific and stereoselective?, A stereospecific mechanism specifies the stereochemical outcome of a given reactant, whereas a stereoselective reaction selects products from those made available by the same, non-specific mechanism acting on a given reactant.
Furthermore, What is a stereospecific in organic chemistry?, Illustrated Glossary of Organic Chemistry – Stereospecific. Stereospecific: A reaction in which the stereochemistry of the reactants controls the outcome of the reaction.
Finally, How do you know if a reaction is stereospecific?, Consider the stereochemical features of the reactants to determine stereospecificity or lack thereof. o If another stereoisomer of the reactant will give identical products in identical ratios, then the reaction is not stereospecific. o If a different stereoisomer of the reactant or reagent gives a stereoisomerically …
Frequently Asked Question:
What are stereospecific reactions examples?
There are actually quite a few examples of other stereospecific reactions. The hydroboration reaction is one (cis addition), as is catalytic hydrogenation (gives cis products), addition of bromine to double bonds (anti products), epoxidation, cyclopropanation, the Diels Alder, and more.
Which reactions are stereospecific?
8 Stereoselective reactions
- Nucleophilic addition to a homochiral cyclic ketone.
- Nucleophilic addition to a racemic cyclic ketone.
- Enantioselective hydride reduction of carbonyl compounds.
What is stereoselective reaction with example?
Examples. An example of modest stereoselectivity is the dehydrohalogenation of 2-iodo-butane which yields 60% trans-2-butene and 20% cis-2-butene. Since alkene geometric isomers are also classified as diastereomers, this reaction would also be called diastereoselective.
How do you know if a reaction is stereospecific or not?
Consider the stereochemical features of the reactants to determine stereospecificity or lack thereof. o If another stereoisomer of the reactant will give identical products in identical ratios, then the reaction is not stereospecific. o If a different stereoisomer of the reactant or reagent gives a stereoisomerically …

How do you know if something is stereospecific?
Consider the stereochemical features of the reactants to determine stereospecificity or lack thereof. o If another stereoisomer of the reactant will give identical products in identical ratios, then the reaction is not stereospecific. o If a different stereoisomer of the reactant or reagent gives a stereoisomerically …
What makes a reaction stereospecific?
In general, one stereoisomer of certain reactant produces one stereoisomer of a certain product, whereas a different stereoisomer of the same reactant produces a different stereoisomer of the same product. The addition of molecular bromine to 2-butene is stereospecific.
How do you know if a reaction is stereoselective?
If more than one reaction could occur between a set of reactants under the same conditions giving products that are stereoisomers and if one product forms in greater amounts than the others, the overall reaction is said to be stereoselective.
What are stereospecific reactions examples?
There are actually quite a few examples of other stereospecific reactions. The hydroboration reaction is one (cis addition), as is catalytic hydrogenation (gives cis products), addition of bromine to double bonds (anti products), epoxidation, cyclopropanation, the Diels Alder, and more.
What is meant by stereospecific reaction?
In chemistry, stereospecificity is the property of a reaction mechanism that leads to different stereoisomeric reaction products from different stereoisomeric reactants, or which operates on only one (or a subset) of the stereoisomers.
How do you know if a reaction is stereospecific?
Consider the stereochemical features of the reactants to determine stereospecificity or lack thereof. o If another stereoisomer of the reactant will give identical products in identical ratios, then the reaction is not stereospecific. o If a different stereoisomer of the reactant or reagent gives a stereoisomerically …
What is difference between stereoselective and stereospecific?
Stereospecific and stereoselective reactions are two types of reaction that can be found in organic chemistry. The main difference between stereospecific and stereoselective reactions is that a stereospecific reaction gives one specific product whereas stereoselective reaction gives multiple products.
