Theory of Meta directing group
The substituent, S takes electrons from para and ortho positions. So, m-position becomes a position of comparatively high electron density and further substitution through electrophile occurs at Meta position. For instance, -NO2 group is a Meta directing (Electron withdrawing). Its procedure can be demonstrated as:
All meta-directing sets comprise either a partial positive charge or a full positive charge on the atom straight attached to the ring.

Q. Determine the frequency of light wave? Ans. The wavelength of red light is 7.0 x 10 -7 m. What is the frequency? c = λv The first thing to remember here is that
Average rate of a reaction is defined as the rate of change of concentration per unit time. It is calculated by dividing the total change in concentration of any one of the react
