(i) Give the structure of the product formed when an acidified solution of compound A is reacted with Naphthalen-2-ol (2-naphthol) and Sodium cyanide separately
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 5o 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.
Question: Answer both (i) and (ii) below
(i) Give the structure of the product formed when an acidified solution of compound A is reacted with Naphthalen-2-ol (2-naphthol) and Sodium cyanide separately
(ii) 1g of phenylamine yielded 1.2g of compound A. Calculate the percentage yield of the reaction.
