What is free racial ??

In a bond it contains 2 eletron right.

If undergo homolytic cleavage then free radical generates

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

see

See this

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

yes

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

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??

please ask if any doubt

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

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

This occurs due to electronegativity differences

I cannot understand clearly

okk wait

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

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

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

like when Br2 breaks to 2Br...

so outer most orbital consist of same number valence electrons

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

will some elements undergoes free radical or all elements ..

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

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