In KMnO4, oxidation state of Mn is +7. As the oxidation state of atom increases, the element become more electronegative in nature. Mn gain 5 electron in acidic medium and reduces to +2 oxidation state. Gain of 5 electron shows that the electronegativity of Mn has increased. Therefore, KMnO4 is a good oxidizing agent. Note: […]

Solution: Bond angle is inversely proportional to electronegativity of substituents. i.e., Electronegativity of side atom increase then the bond angle (X-P-X) decreases. So, X-P-X or F-P-F bond angle is least in POF3. That’s why the O-P-F is maximum. Hence, the correct order of bond angle for O-P-X in the given molecules

The equal volume of two HCl solutions of pH=3 and pH=5 were mixed. What is the pH of the resulting solution? To calculate the pH of the resulting solution from the two solutions whose pH values are known. Firstly, calculate hydrogen ion concentration of both the solutions with the help of pH formula. We know
