When the transfer of electrons takes place waya from the attacking reagent, it is -E effect eg. Addition of cyanide ion to carbonyl compounds

When the transfer of electrons takes place towards the attacking reagent, it is +E effect. Eg. Addition of acids to alkenes

Electrolysis involves electronation and de-electronation at the respective electodes. Anode electrolytic cell is the electode at which de-electronation takes place whereas at cathod electronation is noticed. If two or more ions of same charge are to be electonated or deelectronate the ion having lasser discharge potential is discharged. Discharge potential of anion refers for EP_(OP)^(@) of E_("RP")^(@) as the case may be. The products formed at either electode is given in terms Faraday's laws of electrolusis i.e. w=(Eit)/(96500) During electrolysis of CuSO_(4(aq)) , the pH of solution becomes

According to molecular orbital theory, atomic orbitals of nearly same energy of different atoms are combined and form molecule. In homodiatomic molecule two atomic orbitals which have wave function psi_(A) and psi_(B) are combined in two ways (psi_(A)pm psi_(B)) . They have two type of electron density, one is bonding [(psi_(A) pm psi_(B))^(2)] where e- density increase between nucleus. Another is antibonding [(psi_(A)pm psi_(B))^(2)] where e^(-) density decreases between nucleus. These molecular orbitals are filled according to Hund, Pauli, afbau principle. Existence of molecule depends on bond order. where bond order = ("Number of bonding "e^(-)"s- number of antibonding "e^(-)s)/(2) lf the molecule have unpaired electron it is paramagnetic otherwise diamagnetic Statement- 1: Removal of two e^(-) from N^(2) , magnetic behaviour does not change while addition of two electrons in O_(2) magnetic behaviour changes. Statement-2: In N_(2) removal of electron talces place from bonding orbital while addition of e^(-) in O_(2) is in antibonding orbital

CO is an unsaturated compound because all the valencies of carbon are not satisfied and forms addition compounds e.g. It forms carbonyl sulphide (COS ) with sulphur, carbonyl chloride ( phosgene COCl_(2) ) with chlorine, sodium formate with NaOH , methyl alcohol with H_(2) in the presence of ZnO//Cr_(2)O as catalyst) A overset("Red hot coke")(rarr)CO overset(Cl_(2))(rarr)C overset(H_(2)O)(rarr)2HCl+A .
