$1-$Pentanol

Vedclass · Answer

(D) The dehydration of alcohols to form ethers using a trace of sulphuric acid follows an $S_N2$ mechanism. Primary alcohols are the least sterically hindered and therefore undergo $S_N2$ substitution most readily to form ethers. Secondary and tertiary alcohols are more prone to elimination reactions (forming alkenes) due to steric hindrance and the stability of the carbocation intermediate. Among the given options,$1-$Pentanol is a primary alcohol,while the others are secondary or tertiary alcohols. Therefore,$1-$Pentanol gives the best yield of dialkyl ether.

Column-$I$ (Compound)	Column-$II$ (Major Product)
$A$. $1$-Methylcyclohexanol	$i$. $1$-Methylcyclohexene
$B$. Butan-$1$-ol	$ii$. But-$1$-ene
$C$. tert-Butyl alcohol	$iii$. Isobutylene
$D$. Butan-$2$-ol	$iv$. But-$2$-ene

Which of the following alcohols gives the best yield of dialkyl ether on being heated with a trace of sulphuric acid?
