    Atoms and molecules are too small to count. To solve this problem their numbers are expressed in terms of Avogadro’s number (NA = 6.023 1023).  Mole is the number equal to Avogadro’s number just like a dozen is equal to 12, a century means 100, a score means = 20.

    Mole can be defined as  a unit which represents 6.023 x1023 particles of same matter.

    The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency. The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number. The number of secondary valences is fixed for every metal atom.

    • In haloarenes there is delocalisation of electrons due to resonance.
    • The short bond length (1.69A0) imparts stability to aryl halides and the bond cleavage becomes rather difficult.
    • The aryl halides are therefore less reactive than alkyl halides.
