• # question_answer An organic compound contains $C=38.8%,$ $H=16%$ and $N=45.2%$. Empirical formula of the compound is [CPMT 1973, 83] A) $C{{H}_{3}}N{{H}_{2}}$ B) $C{{H}_{3}}CN$ C) ${{C}_{2}}{{H}_{5}}CN$ D) $C{{H}_{2}}{{(NH)}_{2}}$

Therefore, Empirical formula = $C{{H}_{5}}N$ or $C{{H}_{3}}N{{H}_{2}}$.
