MCQ
An organic compound on analysis gave the following results : $C = 54.5\%, \,O = 36.4\%, \,H = 9.1\%$. The Empirical formula of the compound is
  • A
    $C{H_3}O$
  • ${C_2}{H_4}O$
  • C
    ${C_3}{H_4}O$
  • D
    ${C_4}{H_8}O$

Answer

Correct option: B.
${C_2}{H_4}O$
b
(b)

Element            No. of Moles        Simple Ratio                            

 $C = 54.5$

 $54.5/12 = 4.54$

        $2$

 $H = 9.1$

 $9.1/1 = 9.1$

        $4$

 $O = 36.4$

 $36.4/16 = 2.27$

         $1$

 

 Hence, $C_2H_4O$.
