C能与羧酸反应、能在Cu加热条件下与氧气反应，C含有羟基-OH，由C、D、E转化可知，三者含有相同碳原子数目，C、E生成F，F的分子式为C4H4O4，故C中含有2个C原子，由A、B、C的转化可知，A中含有2个C原子，A是化学工业重要原料之一，能与溴反应，故A为CH2=CH2，B为BrCH2CH2Br，C为HOCH2CH2OH，D为OHC-CHO，E为HOOC-COOH，F为，乙二醇与丙烯酸发生酯化反应生成G，结构G的分子式可知，G为CH2=CHCOOCH2CH2OH，乙二醇与CH3CH2COOH发生酯化反应生成I，根据I的分子式可知，I为CH3CH2COOCH2CH2OH，（1）通过以上分析知，A的结构简式为：CH2=CH2，F为，
G为CH2=CHCOOCH2CH2OH，在一定条件下发生加聚反应生成高聚物H，
故答案为：CH2=CH2，，加聚反应；
（2）①C→I是乙二醇与CH3CH2COOH发生酯化反应生CH3CH2COOCH2CH2OH，反应方程式为：
CH3CH2COOH+HOCH2CH2OH
