Question

The following is an experimental account of the preparation of compound B from Phenylamine.

2cm³ of phenylamine are dissolved in 10cm³ of 0.5M hydrochloric acid in a test tube and cooled in an ice bath. 5cm³ of 0.2M sodium nitrate solution cooled to about 5^o are added to the solution above and shaken. A salt A, C₆H₅N₂Cl is formed, collected and dried. 1g of salt A is dissolved in 10cm³ of water, cooled and added drop by drop to a cold solution of 0.3g phenol in 5cm³ of 0.1M sodium hydroxide solution. B is precipitated, filtered, dried and the melting point determined. B is further crystallized twice and the melting point taken each time and found to be constant.

Give the structure of the product formed when an acidified solution of compound A is reacted with

(i)Naphthalen-2-ol (2-naphthol)

(ii) Sodium cyanide
