How to Isolate Organics ─ Part 1

The separation science did not begin with sophisticated analytical instruments but did in wet labs.


A separation process is a scientific method or technique that converts a mixture or a solution of chemical substances into two or more distinct product mixtures to obtain purity.

Separation may involve physical and/or chemical processes.

Question:

How would you separate a mixture of 1,3-Dinitrobenzene, 3-Nitroaniline, 3-Nitrobenzoic acid and 3-Nitrophenol?

How to Predict where an Electrophilic Aromatic Substitution May Occur in a Ring – Part 3

Image
An organic reaction in which an atom attached to an aromatic system (usually hydrogen) is substituted by an electrophile is referred to as  electrophilic aromatic substitution  ( S E Ar  or  EAS ). One of the most important  EASs  is halogenation. If Bromine water is added to Aniline, a multi-substituted product ( 2,4,6 -derivative) is obtained as Aniline is a strongly activating group (the same happens to Phenol). To generate the mono-substituted product, a protection, say, an acyl group is required.

How to Carry out a Multistep Synthesis – Part 4

Image
Multistep synthesis  is the artificial execution of multiple organic chemical reactions to obtain one or more products by physical and chemical manipulations. Retrosynthetic analysis is a problem-solving approach in the organic syntheses, achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents, and repeated until a simple or commercially available structure is reached, which can be used as a starting material to synthesize the target molecule. Question: How would you do the following transformation?
