由G可知F为CH3CH=CHCOOCH2CH2CH3,则C为CH3CH=CHCOOH,E为CH3CH2CH2OH,B为CH3CH=CHCHO,D为CH3CH2CH2Br, A在一定条件下发生消去反应,能得到两种互为同分异构体的产物,应为
, (1)A→B生成C=C官能团,发生消去反应,F为CH3CH=CHCOOCH2CH2CH3,含有C=C,发生加聚反应生成G, 故答案为:消去反应;加聚反应; (2)由以上分析可知A为
, 故答案为:
‘ (3)D为CH3CH2CH2Br,在碱性条件下发生水解生成E,反应的方程式为CH3CH2CH2Br+NaOHCH3CH2CH2OH+NaBr 或CH3CH2CH2Br+H2OCH3CH2CH2OH+HBr,C为CH3CH=CHCOOH,与E发生酯化反应, 反应的方程式为CH3CH2CH2OH+CH3CH=CHCOOHCH3CH=CHCOOCH2CH2CH3+H2O, 故答案为:CH3CH2CH2Br+NaOHCH3CH2CH2OH+NaBr或CH3CH2CH2Br+H2OCH3CH2CH2OH+HBr; CH3CH2CH2OH+CH3CH=CHCOOHCH3CH=CHCOOCH2CH2CH3+H2O; (4)A为
,酯类同分异构体有CH3COOCH2CH3、HCOOCH2CH2CH3、CH3CH2COOCH3、HCOOCH(CH3)2, 故答案为:CH3CH2COOCH3;HCOOCH(CH3)2. |
