Solution

(i) Diethyl ether from Ethanol:
$C_{2} H_{5} O H + H_{2} S O_{4} 110 - ----- \to C_{2} H_{5} H S O_{4} + H_{2} O$
$C_{2} H_{5} H S O_{4} + C_{2} H_{5} O H 140 - ----- \to C_{2} H_{5} O C_{2} H_{5} + H_{2} S O_{4}$
Diethyl ether
(ii) Ethanol from Diethyl ether:
$C_{2} H_{5} O C_{2} H_{5} + H_{2} O C o n c . H_{2} S O_{4} - ---------- \to 2 C_{2} H_{5} O H$
Ethanol
(iii) Ethyl acetate from Ethanol:
$C_{2} H_{5} O H + C H_{3} C O O H H_{2} S O_{4} - -------- \to E s t e r i f i c a t i o n C H_{3} C O O C_{2} H_{5} + H_{2} O$
Ethyl Acetate
(iv) Ethanol from Glucose:
$C_{6} H_{12} O_{6} Y e a s t (Z y m a s e) - -------- \to F e r m e n t a t i o n 2 C_{2} H_{5} O H + 2 C O_{2}$
Ethanol
