Q16 / 90 · JEE Main 2024 (05 Apr Shift 1) · Chemistry

An organic compound has \(42.1 \%\) carbon, \(6.4 \%\) hydrogen and remainder is oxygen. If its molecular weight is 342, then its molecular formula is :

  • A
    \(\mathrm{C}_{11} \mathrm{H}_{18} \mathrm{O}_{12}\)
  • B
    \(\mathrm{C}_{12} \mathrm{H}_{20} \mathrm{O}_{12}\)
  • Correct answer
    C
    \(\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}\)
  • D
    \(\mathrm{C}_{14} \mathrm{H}_{20} \mathrm{O}_{10}\)

Solution

only $\mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}$ has $42.1 \%$ carbon, $6.4 \%$ hydrogen $\& 51.5$ percent oxygen.

Hence, the correct answer is option: 'C'.
