Why CH3 group is Ortho and para directing in? Toulene
IN CASE OF TOLUENE the methyl group attached to the ring, increases the electron density at ortho and para positions by resonance without changing anything at the meta position. Thus […]
Why is water more acidic than alcohol?
THE ANSWER CAN BE UNDERSTOOD EASILY BY LOOKING AT THE FOLLOWING POINTS:- 1. In case of alcohol the Oxygen atom is joined to the alkyl group on one side and […]
What causes Ionic bonds to form? Use NaCl (table salt) as an example to explain the formation of ionic bonds.
it is a very common question and common example too. i would love to answer. Most people say it is the bond formed due to the transfer of electrons, but this explanstion is not complete. Ionic bond is the bond formed due to strong electrostatic forces of attraction between two oppositely charged ions. here is the complete reaction that takes […]
Which is more acidic ortho methyl phenol or phenol?
the phenol is more acidic as compared to ortho methyl phenol because the methyl group is electron releasing group which will increase the electron density in the ring as well […]
The galvanised iron lost its zinc coating even after it doesn’t corrode. Why does this happen?
Lets look from a different angle corrosion is basically oxidation and in oxidation the electrons are lost. Here we have zinc coated on iron being more reactive the zinc will tend to loose the electrons even if the iron is exposed, even then being good conductor the electrons are given to the iron by the zinc. So actually the lost […]
The second electron affinity of oxygen is positive, what does that mean?
Electron affinity is the amount of energy change during the addition of an electron to an isolated gaseous atom. It can be positive as well as negative. Negative electron affinity means that the energy is released during the addition of electron. Which is a favorable condition for gaining an electron. But positive value means that we have to supply 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 they are present […]
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 […]
Why Alkynes are less reactive than alkenes towards electrophilic addition reaction ?
There are two reasons for less reactivity of Alkynes towards electrophillic addition reactions:- Due to greater electronegativity of sp-hybridized carbon atoms of a triple bond than sp2 -hybridized carbon atoms of a double bond, pie-electrons of alkynes are more tightly held by the carbon atoms than pie electrons of alkenes and hence are less easily available for reaction with electrophiles.
