how we can prepare carboxylic acid (benzoic acid) from acyl halides and acid anhydrides (benzoic anhydride)

Preparation of carboxylic acids from acyl halides is a simple method in which the acid chloride or halide is hydrolysed to give carboxylic acids. The general reaction and examples are given below.. The hydroxyl group (OH group) present in water replaces the halide atom and thus forms the carboxylic acid. Various acids are formed by

Preparation of chlorobenzene – Sandmeyer’s reaction

Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction. The reaction is named after the Swiss Chemist Traugott Sandmeyer. In this reaction the diazonium group losses the molecule of dinitrogen and it yields chlorobenzene.

What are the methods of preparation of Aldehydes and Ketones ?

What are the methods of preparation of Haloalkanes and haloarenes ?

What are the methods of preparation of Carboxylic Acids ?

Carboxylic acids are prepared by various methods like oxidation of primary alcohols, oxidation of aldehydes and ketones, hydrolysis of nitriles, grignard reagents, hydrolysis of esters etc.

Why isn’t water inflammable? It is made of flammable chemicals which are hydrogen and oxygen.

This is a best example to share when we talk about chemical change, that the products have totally different properties from that of the reactants , from which they are made. Now coming to the answer, Formation of water is a highly exothermic type of reaction and a lot of energy is lost at the

What is the hybridisation of Cl2? Is it different from the hybridisation of F2 molecules?

Here you can see the hybridization of both is same , both of these two elements have seven electrons in outermost shell and below is the diagram showing the electrons filled in s-subshell and p-subshell . one orbital of s- subshell and three orbitals of p-subshell are used during hybridisation. So the type of hybridization

Various separating methods

We come across the various kind of mixtures in our daily life that have different kind of components and sometimes we have to separate the components for our benefit and there comes the need of separation in our day to day life.  we do separation by using different kind of separating techniques. some techniques Are
