Sample A has a melting range of 141 145 C and sample B has a

Sample A has a melting range of 141- 145 °C and sample B has a melting range of 146-147C. A finely ground mixture of A and B has a melting range of 143-146 OC. From these results we may conclude. (a) A and B are the same compound, and no information on relative purity is 3. available from this data. (b) A and B are different compounds (c) A and B are the same compound and are of similar purity (d) A and B are the same compound, but B is more pure than A (e) A and B are the same compound, but A is more pure than B

Solution

D becoz the compount which have impurity or mixing melt at low temp so .A and B is same comp but B Is more pure then A
