Question

Which of the following compounds is NOT isomeric with ethoxy ethane?

पर्याय

• 2-Methylbutan-2-ol

• 1-Methoxy propane

• 2-Methylpropan-2-ol

• 2-Methoxy propane

Answer 1

2-Methylbutan-2-ol

Explanation:

\[\ce{\underset{\text{Ethoxy ethane}}{H3CCH2 - O - CH2CH3}}\]	\[\ce{\underset{\text{l - Methoxy propane}}{H3C - O - CH2CH2CH3}}\]
\[\begin{array}{cc} \ce{OH}\\|\\ \ce{H3C - C - CH3}\\ |\\\ce{CH3}\end{array}\]	\[\begin{array}{cc} \ce{H3C - CH - CH3}\\ |\phantom{..}\\ \phantom{...}\ce{OCH3}\end{array}\]
2 - Methyl propan - 2- ol	2 - Methoxypropane
Molecular formula for all above 4 structure is same (C4H10O)

\[\begin{array}{cc}
\phantom{........}\ce{OH}\\
\phantom{.......}|\\
\ce{H3C - CH2 - C - CH3}\\
\phantom{.......}|\\
\phantom{.........}\ce{CH3}\end{array}\]

2 - Methyl butan - 2- ol

M.F. = C₅H₁₂O
