．分子式为的有机物含有一个六元环结构，在酸性条件下发生水解，

．分子式为的有机物含有一个六元环结构，在酸性条件下发生水解，产物只有一 种，又知该有机物的分子中含有两个甲基，则该有机物的可能结构有

A．6 种             B．8 种             C．10 种            D．14 种

答案

【答案】C

【解析】

由题目水解产物只有一种知C7H12O2为环酯，所以分子式为C7H12O2为饱和环酯，可推测该有机物环上含有一个“-COO-”的六元环，环上其余为4个碳原子，在环外有两个碳，两个甲基在不同碳原子上，有，有6种；两个甲基在同一碳上，在苯环上有四个碳原子，有四种，共10种，故选C。
