What is syn-anti isomerism?

Syn-anti isomerism in organic chemistry is a type of geometrical isomerism. The prefixes “syn” or “anti” are used to denote geometrical isomers. 

We have discussed geometrical isomerism in previous articles.1 Preferably, syn /anti notations are used for nomenclature of oximes that is aldoxime and ketoxime. Meaning of the word syn is “together” or “with”.  And meaning of the word anti is “opposite”. 

How to Calculate Enantiomeric Excess and Optical Purity?

Optical purity of compound is defined as percentage of major isomer present in the sample of compound.

Key words: Enantiomeric excess, Isomers, Enantiomers, optical purity

Imine - Formation, Reactions, and Mechanisms

In this article we will discuss Imine compounds in chemistry. Here we will learn about formation, reactions, and mechanisms of imine compounds.

Imine is a chemical compound form as result of condensation of carbonyl compound (ketone or aldehyde) and amine.

Grignard Reagents - Reactions, Mechanism, and Handling Procedures

In this article we will discuss about Grignard Reagents - Reactions, Mechanism, and Handling Procedures. 

Grignard reaction is an organometallic chemical reaction. It was discovered by Victor Grignard and he was awarded the Nobel Prize (1912) in Chemistry for this work.
