Question

（15分）有机物A为芳香烃，质谱分析表明其相对分子质量为92，某课题小组以A为起始原料可以合成酯类香料H和高分子化合物I，其相关反应如下图所示：                                                       
已知以下信息：
①碳烯（:CH₂）又称卡宾，它十分活跃，很容易用它的两个未成对电子插在烷烃分子的C-H键之间使碳链增长。
②通常在同一个碳原子连有两个羟基不稳定，易脱水形成羰基。
回答下列问题：

（1）A的化学名称为         。
（2）由B生成C的化学方程式为                ，该反应类型为          。                                                              （3）G的结构简式为           。
（4）请写出由F生成I的化学方程式                                             。
（5）写出G到H的反应方程式                                       。
