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 formedContinue reading “Why sigma bond is stronger than pi bond?”

What is Raoult’s law ?
It states that for a solution of volatile components, the partial vapour pressure of each component is directly proportion to the mole fraction of the component in the solution.
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) +Continue reading “WHY THE IONIC REACTIONS ARE FASTER?”
What are the Differences between elements, compounds, and mixtures ?
In our daily life we come across different kind of particles, some look alike and some we know by common names. tody we are going to arrange almost all the particles around us. Elements :- it is the purest form of matter which has only one kind of atoms. There are 118 elements known tillContinue reading “What are the Differences between elements, compounds, and mixtures ?”
What are the tricks to learn reaction of sodium carbonate with hydrochloric acid?
There is a trick in learning this reaction I will make it very easy for you to learn and rewrite. Firstly see the reaction:- Na2CO3 + 2HCl → 2NaCl + CO2 + H2O Tricks to learn:– Firstly see the formula of carbonate its CO3 , this will be converted into CO2 , One oxygen ofContinue reading “What are the tricks to learn reaction of sodium carbonate with hydrochloric acid?”
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 makesContinue reading “Why is a Cl-Cl bond stronger than an F-F bond?”
What is the difference between molecular mass and formula mass?
In case of ionic compounds we have crystal lattice composed of ions. And there is a never ending pattern of ions and that made it difficult to calculate the molecular mass. Thus we used a simple method by taking the ratio of the ions and then adding their masses, like in case of NaCl ;Continue reading “What is the difference between molecular mass and formula mass?”
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 imagesContinue reading “What is the difference between stereoisomers, optical isomers and enantiomers?”
How does the normality of a mixture equation change for different solutes?
Actually normality depends upon a simple formula that is :- Normality = Number of Gram equivalents / litre The term gram equivalents change as the valency of a substance changes . all the elements do not have same valence and hence it varies from element to element or molecule to molecule. And the term gramContinue reading “How does the normality of a mixture equation change for different solutes?”
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 , ifContinue reading “Neutralisation reaction”
Distillation and fractional distillation.
Distillation is a type of separating process in which two miscible liquids are separated from each other by using their different boiling points. the one with lower boiling point , boils first and its vapours are passed through a condenser for cooling and droplets are received on the other side in a beaker. this processContinue reading “Distillation and fractional distillation.”
