• # question_answer An organic compound containing carbon hydrogen and oxygen contains 52.20% carbon and 13.04% hydrogen. Vapour density of the compound is 23. Its molecular formula will be [MP PMT 2002] A) ${{C}_{2}}{{H}_{6}}O$ B) ${{C}_{3}}{{H}_{8}}O$ C) ${{C}_{4}}{{H}_{8}}O$ D) ${{C}_{5}}{{H}_{10}}O$

Molecular weight = V.D. ´ 2 = 23 ´ 2 = 46 Molecular weight of ${{C}_{2}}{{H}_{6}}O=46$
