    Radicals are uncharge species from Ed by cleavage of the molecule. It maybe because of light or heat. They have a unpaired electron Cation and anion are charged species (+-) without a unpaired electron Radicals are highly reactive than ions. They usually form dimers

    In a bond it contains 2 eletron right.

    If undergo homolytic cleavage then free radical generates

    eduncle-logo-app

    If the bond undergo heterolytic cleavege then cation & anion is generated

    this means the molecule breaks into atom that will be as a reactive atom... with same number of valence electrons

    eduncle-logo-app

    yes

    Free radical is formed by homolytic bond cleavage

    eduncle-logo-app

    Free radicals are formed from molecules via the breakage of a chemical bond such that each fragment keeps one electron

    eduncle-logo-app

    An ion carries a charge, that means that the number of electrons and protons do not match. Electrons have a negative charge and protons have a positive charge. A radical has an unpaired electron, but does not have a net charge because the number of protons equals the number of electrons.

    got this??

    eduncle-logo-app

    please ask if any doubt

    eduncle-logo-app

    that means it breaks as original atom ?? am I correct

    eduncle-logo-app

    no two cleavage mainly occurs...one is homolytic and second one is heterolytic

    eduncle-logo-app

    This occurs due to electronegativity differences

    eduncle-logo-app

    I cannot understand clearly

    eduncle-logo-app

    okk wait

    eduncle-logo-app

    when there is electronegativity difference between two atoms ..then more EN atom withdraws bonding electrons towards itself and cations and anions is formed

    eduncle-logo-app

    and when EN difference is O...then homolytic bond cleavage occurs and each atom acquire one bonding electrons...this is nothing but radical

    eduncle-logo-app

    Then the shared electrons that make bond are taken by the atom that shared then molecules turns to original atom itself ?? am I correct

    eduncle-logo-app

    like when Br2 breaks to 2Br...

    eduncle-logo-app

    so outer most orbital consist of same number valence electrons

    eduncle-logo-app

    yes they share one one bonding electrons which they used for covalent bond

    eduncle-logo-app

    will some elements undergoes free radical or all elements ..

    eduncle-logo-app

    first condition i tell you that no electronegativity differences between both atoms and second presence of light

    eduncle-logo-app

    if n2 molecule undergoes free radical rexn... how many electrons will be there same 1 radical
