Question

Which of the following compounds when heated with $CO$ at $150^{\circ} C$ and $500$ atm pressure in presence of $BF _{3}$ forms ethyl propionate ?

• A. $C_{2}H_{5}OH$
• B. $CH _{3} OCH _{3}$
• C. $C _{2} H _{5} OC _{2} H _{5}$
• D. $CH _{3} OC _{2} H _{5}$

Answer 1

Answer: (C)

$C _{2} H _{5} OC _{2} H _{5}$

Answer 2

Diethyl ether when heated with $CO$ at $150^{\circ} C$ and $500$ atm pressure in presence of $BF _{3}$ forms ethyl propionate. $C _{2} H _{5} OC _{2} H _{5}+ CO \xrightarrow[500 \text { atm }] {150^{\circ} C \Delta}\underset{\text{ethyl propionate}}{ C _{2} H _{5} COOC _{2}H _{5}}$
