Write one general method for the preparation of the following class of compounds with necessary chemical equations: 1+1+1 = 3 Primary alcohol Phenol Ether.

2 Ag^(+1) NO_3^((...)) + Cu^0 → Cu^((...))(NO_3)_2^(-1) + Ag^((...)) . Complete this chemical equation by assigning oxidation numbers.

Case 1: A chemical equation is the representation of chemical change in terms of symbols and formulae of reactants and products. The substances which react are written on the left hand side of the arrow and are termed as reactants while the substances produced as result of reaction are called products and are written on the right hand side of the arrow. The arrowhead shows the direction of the reaction. A chemical equation in the whcih the number of atoms of each element on reactant side is equal to that on the product side is said to be balanced. Which of the following statement is incorrect regarding th significance of the chemical equations?
