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 1 where the leaving group leave with electron pair and leaves behind a carbocation. The whole rate depends only on one molecule. That’s why it
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 ?
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 the rate of reaction, so it is BIMOLECULAR mechanism. The whole mechanism proceeds through a single step. That concerted step involves the bond breaking and
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. This lone pair pushes the bond pairs downwards due to lone pair-bond pair repulsions which decreases the bond angle in P-H-P atoms, as shown below.
NH3 gives deep blue colored mine complex compound on reacting with Cu²+.
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 of the energy in that system was dissipated in the form of heat lost to the surroundings and in overcoming the frictional forces of the
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
non ideal solutions show positive and negative deviations on the basis of intramolecular attractions
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
Molarity : It decreases with increase in temperature. Molality : It remains constant . Doesn’t change.
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.
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. Why the electron affinity or electron
diagram of lone pairs of CS2
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 .

Leave me, I do not mean at all. I wish you look at the expressions Requesting not to leave. Try to listen the noise, Which screams louder Louder than the silence. Try to look behind Behind every smile Drop by drop my heart is Sinking. Feel the heaviness Heaviness of my breath As I ,
We used to walk, And long talks, While eating, Or while having a drink. Whenever he asked any work, I used to wink. My mother’s father, Was a nice friend of mine. We used to spend Great time. We watched movies together, Long discussions about the actors. But long ago he passed, His phone is
Organic inter-conversions , Propene to 1-nitropropane,ethane to bromoethane, ethanol to but-1-yne, Propene to propyne, toluene to benzyl alcohol.
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
Xenon hexafloride has a distorted octahedral geometry.
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
We can if we wish, Returning is never so tough, It’s not mandatory, But it’s a choice, You can say openly, Who suppress your voice, And decision you make, Are not of iron, or steel, You can break them whenever you feel, And life is not a movie, Where you can rewind the reel, The
