                    The general molecular formula, which represents the homologous series of alkanols is:                

    A)                 \[{{C}_{n}}{{H}_{2n}}{{O}_{2}}\]

    B)                 \[{{C}_{n}}{{H}_{2n}}O\]

    C)                 \[{{C}_{n}}{{H}_{2n+1}}O\]

    D)                 \[{{C}_{n}}{{H}_{2n+2}}O\]

    Correct Answer: D

    Solution :

                    Alkanols are the derivatives of alkanes which are derived by the replacement of ?H of alkanes with ?OH (hydroxyl groups)                 \[\underset{\text{Alkanes}}{\mathop{{{C}_{n}}{{H}_{2n+2}}}}\,\xrightarrow[+OH]{-H}{{C}_{n}}{{H}_{2n+1}}OH\] or \[{{C}_{n}}{{H}_{2n+2}}O\]
