(a) In the reaction mechanisms given, there are some chemical species which will get produced in one step and get consumed in the other step and that are not in reactants nor in products of the total reaction. Such species are known as intermediates of a reaction as the name suggests. Therefore, in mechanism 1, the intermediates are (CH3)2CHOH2+, Cl-, (CH3)2CH+. and in mechanism 2: (CH3)2CHOH2+, Cl-.
