    Enthalpy of atomisation depend upon the number of unpaired electron more is unpaired electron more is enthalpy of atomisation.Upto the middle of the series, the number of unpaired electrons increases and then decreases due to their pairing. This results first in the increase and then decrease in the value of enthalpy of atomisation.

    Acid is needed to provide H+(aq) ions, so that this particular reaction occurs. If HCl were used instead of sulphuric acid then permanganate ions would oxidise Cl- ions to Cl2 (g) which would not react with oxalic acid

    species which can donate electron.or simply electron donator are lewis base

    0Thank You

    Yogita Ingle 5 years, 11 months ago

    Atomic or molecular chemical species having a highly localized HOMO (Highest Occupied Molecular Orbital) act as Lewis bases. These chemical species have the ability to donate an electron pair to a given Lewis acid in order to form an adduct, as discussed earlier.

    The most common Lewis bases are ammonia, alkyl amines, and other conventional amines. Commonly, Lewis bases are anionic in nature and their base strength generally depends on the pKa of the corresponding parent acid.

    Examples of Lewis Bases

    Examples of Lewis bases which have an ability to donate an electron pair are listed below.

    • Pyridine and the derivatives of pyridine have the ability to act as electron pair donors.
    • The compounds in which Oxygen, Sulfur, Selenium, and Tellurium (which belong to group 16 of the Periodic Table) exhibit an oxidation state of -2 are generally Lewis bases. Examples of such compounds include water and ketones.

    Aniline is basic in nature and the reagent AlCl3 is acidic so there will occur an acid base reaction in which salt will get form.

    0Thank You

    Rohit Chauhantm 5 years, 11 months ago

    As The catalyst AlCl3 i.e. used in friedel craft reaction react with aniline and give am insoluble compound.

    0Thank You

    Chirag Sharma 5 years, 11 months ago

    Aniline does not undergo Friedel craft's reactions because the reagent AlCl3 (the Lewis acid which is used as a catalyst in friedel crafts reaction), being electron deficient acts as a Lewis base.
