\(Na_2O_2\) is not the superoxide of sodium. It is peroxide of sodium.
The correct superoxide formula for sodium is \(NaO_2\).
So, the correct option is (D): It is the super oxide of sodium.
Ion having highest hydration enthalpy among the given alkaline earth metal ions is:
A point particle of charge \( Q \) is located at \( P \) along the axis of an electric dipole 1 at a distance \( r \) as shown in the figure. The point \( P \) is also on the equatorial plane of a second electric dipole 2 at a distance \( r \). The dipoles are made of opposite charge \( q \) separated by a distance \( 2a \). For the charge particle at \( P \) not to experience any net force, which of the following correctly describes the situation?
