In aqueous potassium hydroxide nucleophilic substitution takes place, however in alcoholic potassium hydroxide elimination takes place. Account for the observation with suitable example

Electrophilic substitution in phenol takes place at

Chloroethane is treated with alcoholic potassium hydroxide. The product formed is

How sex determination takes place in human? Explain with example.

Explain why in anisole electrophilic substitution takes place at ortho and para positions and not at meta position.

In S_(N^(1)) (substitution, nucleophilic unimolecular) reaction, the racemization takes place. It is due to

The nucleophilic substitution reactions taking place in aromatic system are designated as SN Ar In fact aryl halides do not easily undergo nucleophilic substitution under ordinary conditions. However, introduction of electron- withdrawing groups in o, p – positions makes the reaction to go faster. Keeping these general points in view answer the following questions product. The solution is treated with AgNO_3 solution. Which of the following is correct

However, introduction of electron- withdrawing groups in o, p – positions makes the reaction to go faster. Keeping these general points in view answer the following questions Which of the following structures is correct in the mechanism of the reaction

Write the series of reactions of chloroform with hot aqueous solution of potassium hydroxide

Take two beakers and prepare lead nitrate aqueous solution and potassium iodide aqueous solutions. What are the colours of the solutions? Now mix them in another beaker. What happens? What type of chemical reaction it is? What are products?
