How to Make Use of Stoichiometry – Part 1

Stoichiometry is the relationship between the quantities of reactants and products before, during, and after chemical reactions.


A chemical equation is the representation of a chemical reaction in the form of symbols and chemical formulas. The coefficients next to the symbols and formulas of entities are the absolute values of the stoichiometric numbers.

Question:

0.6 g of a sample consisting of only CaC2O4 & MgC2O4 is heated at 500°C, gets converted into CaCO3 & MgCO3. The sample is then weighed 0.465 g. If the sample had been heated to 900°C where the products would be CaO & MgO, what would the mixture of oxides weigh?

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?

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 nitration . Let's keep in mind that the presence of an activating group on the ring may complicate nitration.
