A bicyclic organic molecule has a double bond. a tertiary amine function. a chlorine atom and an ether function. Its molar mass is $215.5\;\frac{g}{mol}$. Find its molecular formula.
General molecular formula: $C_nH_{2n-6}NClO$ $12n$ $+$ $2n$ $-$ $6$ $ +$ $ 14$ $+$ $ 35.5$ $+$ $ 16$ $ = $ $213.5$ $n$ $=$ $11$ $C_{11}H_{16}NClO$
