• # question_answer An organic compound gave the following results $C=53.3%,\text{ }H=15.6,\text{ }N=31.1%,$ mol. wt. = 45, What is molecular formula of the compound? A) ${{C}_{2}}{{H}_{5}}{{N}_{2}}$ B) ${{C}_{2}}{{H}_{5}}N$ C) ${{C}_{2}}{{H}_{7}}N$ D) ${{C}_{2}}{{H}_{6}}N$

Hence, formula = ${{C}_{2}}{{H}_{7}}N$ $(C{{H}_{3}}C{{H}_{2}}N{{H}_{2}})$.
