SN1 mechanism
This mechanism is seen in Nucleophillic Substitution reactions, especially in those compounds in which the Carbon atom is more substituted . The rate of this mechanism depends on the step […]
Why sky appears blue in colour ?
The particles of atmosphere which are of colloidal size can easily scatter the blue component of the light. The wavelength of blue light allows its scattering easily. That’s why it appears blue in colour. Why sky appears blue in colour ?
What is an SN2 mechanism? What is its importance?
This is a type of reaction mechanism that is seen in case of nucleophillic substitution reactions. It is BIMOLECULAR NUCLEOPHILLIC SUBSTITUTION mechanism. In this kind of mechanism two molecules decide […]
You are lucky!!!
These three words are commonly seen in the marketing industry just to sell their products. Everyone wishes to be lucky and once they see these magical words their psychological balance tilts towards the tempting offers and the whole affair ends up in just selling what they want to sale. I am not saying that we are not lucky, yes we […]
Why Bond angle in PH4+ is higher than in PH3 ?
In case of both molecules the hybridization of P is sp³ but there is a difference. In case of PH3 we have a lone pair present on the phosphorus atom. […]
How NH3 react with solution of Cu²+ ?
NH3 gives deep blue colored mine complex compound on reacting with Cu²+.
What are fuel cells?
This is a very new concept in the field of energy . The conventional energy generators were having a maximum efficiency of approximately 52%. Which is very low . Most […]
What dissolves faster in water, salt or sugar?
For this we have to understand that the nature of water is polar. And salt is an ionic compound which is also polar in nature. But sugar is non polar in nature and thus it have a different nature. The dissolution of substances follow a simple rule ,”Like dissolves like.” So salt will dissolve faster than sugar.
Give one example each of miscible liquid pairs showing positive and negative deviations from Raoult’s law. Give reason for such deviation.
non ideal solutions show positive and negative deviations on the basis of intramolecular attractions
When the value of Van’t Hoff factor is more than one , and when it is less than one ?
When the molecules of solute undergo dissociation in the solution , the Van’t Hoff factor is more than one. When the molecules of solute undergoes association , the van’t Hoff factor is less than one
What is the effect of temperature on Molarity and Molality ?
Molarity : It decreases with increase in temperature. Molality : It remains constant . Doesn’t change.
What is the number of electrons that an atom can give to or accept from another atom in a chemical reaction?
The maximum number of electrons that can be donated or accepted is 3. The bond formed by the transfer of electrons is ionic bond. Beyond this the sharing of electrons will take place. And the type of bond will be covalent.
Why is chlorine electron withdrawing?
Chlorine being the 2nd member of group 17 elements also known as the halogens have a strong electron affinity. And due to its high electronegativity and electron gain enthalpy ,it shows electron withdrawing nature. We can refer to the following post to get in depth knowledge of the concept. https://theunconditionalguru.in/2021/01/08/why-the-electron-affinity-or-electron-gain-enthalpy-of-chlorine-is-higher-than-fluorine-even-if-fluorine-is-most-electronegative-element/
In carbon disulfide, how many lone pairs of electrons are on each sulfur atom?
diagram of lone pairs of CS2
In a double covalent bond, how many total electrons are being shared?
In a single covalent bond , two electrons are shared , one from each of the atoms taking part in bond formation. So here in case of double bond we have four electrons . In case double bond we have a sigma bond and a pie bond .

What are isoelectric species? And What determines the difference in the size of atoms or ions if they are isoelectronic ?
Isoelectric species are simply the atoms or ions that have same number of electrons. For example:- Na+ , Ne , F- , O²- , Mg²+ And their size depends upon the effective nuclear charge , in case of cations the number of protons is higher than that of electrons thus their size is smaller than […] What are isoelectric species?

Why aeroplane leaves behind white trail in winters or cool weather ?
Hi guys today we are going to talk about the white trail formation during the winter, when an aeroplane flies. Picture credits unsplash.com To understand this phenomenon we must be aware of the combustion process taking place at the time of working of engine. During the combustion process, carbondioxide and water vapours are the major […] Why aeroplane leaves behind […]
