Formation of diethyl ether from ethanol is based on a
1 Dehydration reaction
2 Dehydrogenation reaction
3 Hydrogenation reaction
4 Heterolytic fission reaction
Explanation:
(a) Dehydration of alcohols gives ethers.
ALCOHOLS, PHENOLS AND ETHER

In the commercial manufacture of ethyl alcohol from starchy substances by fermentation method, which enzymes stepwise complete the fermentation reaction
15057
Primary alcohols can be obtained from the reaction of the \(RMgX\) with
1 \(C{O_2}\)
2 \(HCHO\)
3 \(C{H_3}CHO\)
4 \({H_2}O\)
Explanation:
For \(HCHO\), \(RMgX + HCHO \rightarrow RCH _2 OH\) For \(CH _3 CHO\) \(RMgX + CH _3 CHO \rightarrow R \left( CH _3\right) CHOH\) For \(H _2 O\) \(RMgBr + H _2 O \longrightarrow RH + Mg ( OH ) Br\) For \(CO _2\) \(RMgBr + CO _2 \rightarrow RCOOH\) All reactions are followed by hydrolysis to give respective compounds. Only for \(HCHO\), primary alcohol is produced.
