Why sigma bond is stronger than pi bond?

Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formed is not so strong as […]

WHY THE IONIC REACTIONS ARE FASTER?

How are reactions related to chemical bonds? The type of bond has a great effect on the rate of reaction or speed of reaction. Here we are going to discuss why and how it happens, First of all in case of ionic compounds:- Lets take example of Sodium hydroxide and Hydrochloric acid NaOH (aq) + HCl (aq) →  NaCl + […]

Why is a Cl-Cl bond stronger than an F-F bond?

This is due to the following two major reasons :- The fluorine atoms are very small in size . The florine element is having the highest electronegativity. Due to these two reasons the florine atoms are so near after the F-F bonding that the start repelling each other due to higher electron desity, which makes it easy to break the […]

What is the difference between stereoisomers, optical isomers and enantiomers?

Stereoisomers :- These are the compounds that have same molecular formula but different arrangement of atoms in the space. Optical isomers :- The compunds that have same molecular formula but they rotate the plane polarised light to the different side, right side-dextrorotatory and left levorotatory. Enantiomer :- These are the compounds that are mirror images of each other and if […]

Neutralisation reaction

The reaction between an acid and base to give salt and water is called neutralisation reaction. here in the following reaction we can easily see how Hydrochloric acid is reacting with sodium chloride NaOH + HCl ———> NaCl + H2O the nature of salt formed is dependent on the type of acid or base , if there is any difference then […]
