A) Give the reagents and reaction conditions for the conversions (i), (ii), (iii) and (iv)

Here's the solution to the organic chemistry problem:

a) Give the reagents and reaction conditions for the conversions (i), (ii), (iii) and (iv)

Conversion	Reagent(s)	Reaction conditions
(i)	Potassium cyanide ($\text{KCN}$)	Ethanolic, heat (reflux)
(ii)	Dilute hydrochloric acid ($\text{HCl}$)	Heat (reflux)
(iii)	Aqueous potassium hydroxide ($\text{KOH}$)	Heat (reflux)
(iv)	Aqueous potassium hydroxide ($\text{KOH}$)	Heat (reflux)
