【题目】已知。分析下图变化,试回答下列问题:(E没有支链)

(1)写出下列有机物的结构简式:

A___________________C _______________________E ____________________F_________________

(2)写出下列有关反应的化学方程式:

C →D_______________________

D →E_______________________

E→F_______________________

【答案】 CH3-CH=CHCOOCH3 CH3CH=CH-COOH+H2O CH3CH=CH-COOH+CH3OH CH3-CH=CHCOOCH3+H2O n CH3-CH=CHCOOCH3

【解析】已知。分析下图变化,试回答下列问题:(E没有支链)

(1)根据A生成B的条件结合信息和E没有支链可知,A发生信息中反应生成 B,根据A的分子式可知,ACH3CH2CHOAHCN发生加成反应生成BCH3CH2CHOHCNB水解得CCH3CH2CHOHCOOHC在浓硫酸作用下加热发生消去反应得DCH3CH=CHCOOHD发生酯化反应生成EECH3CH=CHCOOCH3E发生加聚反应得F。综上所述,ACH3CH2CHOCCH3CH2CHOHCOOHECH3CH=CHCOOCH3F,故答案为:CH3CH2CHOCH3CH2CHOHCOOHCH3CH=CHCOOCH3

(2)C →D的化学方程式为CH3CH=CH-COOH+H2OD →E的化学方程式为CH3CH=CH-COOH+CH3OH CH3-CH=CHCOOCH3+H2OE→F的化学方程式为CH3-CH=CHCOOCH3;故答案为:CH3CH=CH-COOH+H2OCH3CH=CH-COOH+CH3OH CH3-CH=CHCOOCH3+H2On CH3-CH=CHCOOCH3
