Question

Compound with molecular formula C₃H₆O can show ______.

विकल्प

• Positional isomerism

• Both positional isomerism and metamerism

• Metamerism

• Functional group isomerism

Answer 1

Compound with molecular formula C₃H₆O can show functional group isomerism. 

Explanation:

For a compound with formula

`\implies` C_aH_bN_cO_dX_e

Degree of unsaturation = `1/2(2 + 2a - b + c - e)`

For C₃H₆O, a = 3; b = 6

Degree of unsaturation = `1/2(2 + 2 xx 3 - 6)` = 1

So, given compound contains one double bond.

Hence, possible isomer can be written as follows :

\[\begin{array}{cc}
\phantom{.......}\ce{O}\phantom{...............}\ce{O}\phantom{}\\
\phantom{.......}||\phantom{................}||\phantom{}\\
\phantom{}\ce{CH3 - CH2 - C - H and CH3 - C - CH3}
\end{array}\]

They are functional group isomerism.
