What is vapour phase nitration?

What is Luteal phase.

Which is the active species for the nitration ?

Give two requirements for vapour phase refining.

When an ideal binary solution is in equilibrium with its vapour, molar ratio of the two components in the solution and in the vapour phase is:

For an ideal binary liquid solution with P_A^@> P_B^@ which relation between X_A (mole fraction of A in liquid phase) and Y_A (mole fraction of A in vapour phase) is correct, X_B and Y_B are mole fraction of B in liquid and vapour phase respectively

What is the electrophile produced in a nitrating mixture used for the nitration of benzene?
