Question

What is molecular formula of cyclohexylamine?

• A. $C_{6}H_{8}N$
• B. $C_{6}H_{10}N$
• C. $C_{6}H_{12}N$
• D. $C_{6}H_{13}N$

Hint:

To find the molecular formula of a substituted cycloalkane, start with the base cycloalkane formula ($C_{n}H_{2n}$). For each substituent, subtract one hydrogen from the ring and add the atoms of the substituent. For cyclohexylamine, it's $C_{6}H_{12} - H + NH_{2} = C_{6}H_{11}NH_{2}$, which simplifies to $C_{6}H_{13}N$.
