Some Basic Concepts of Chemistry

An organic compound contains 78% (by weight) carbon and the remaining percentage of hydrogen. The right option for the empirical formula of this compound is (atomic weight of C is 12, H is 1):

  1. A.CH
  2. B.CH2\mathrm{CH_2}
  3. C.CH3\mathrm{CH_3}✓
  4. D.CH4\mathrm{CH_4}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
