Why is carbon important for forming complicated molecules? Or why carbon makes a large number of molecules ?

The answer to this question is very simple . There are two major reasons behind it. 1. Catenation :- It is the property by which the carbon can make long chains, branched chains and ring or cylic structural by joining with its own atoms. Due to this it can make a variety of molecules. 2.

Why H3PO3 is a diprotic acid? Give reason with structure .

Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its structure. Here it have only two hydroxyl groups that is -OH groups, and the hydrogen atoms joined to these only are ionisable. So only these

Why we add coolent in the radiator of car ?

How does a radiator of car works? We all are familiar with the coolent that is normally used in radiators but many of us will admit that they don’t know how it works. Well, being a chemistry geek here I will discuss how it works. Ethylene glycol is the liquid that is widely used in

What is a racemic mixture?

On the basis of Optical activity the compounds or isomers can be classified into two types:- Those rotate the plane polarised light towards right called the dextro rotatory compounds. Those rotate the plane polarised light towards left are called Laevo rotatory compounds. The equimolar composition of the above two isomers is called racemic mixture.

How to find a lone pair in simple way?

Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency and use the electrons for making the bonds. Step3: Now see if there are any unshared electrons pairs. These are your lone pairs. See the
