15g A完全燃烧生成22g CO
2和9.0g H
2O,二氧化碳物质的量为
=0.5mol,m(C)=0.5mol×12g/mol=6g,水的物质的量为
=0.5mol,则m(H)=0.5mol×2×1g/mol=1g,故m(O)=15g-6g-1g=8g,则n(O)=
=0.5mol,则A中C、H、O原子数目之比为0.5mol:1mol:0.5mol=1:2:1,则A的最简式为CH
2O,令A的组成为(CH
2O)x,质谱法测得A的相对分子质量为90,则30x=90,故x=3,则A的分子式为C
3H
6O
3,结合转化关系可知A中含有-COOH,A的核磁共振氢谱有四个峰,峰面积之比为1:1:1:3,则A为CH
3CH(OH)COOH,两分子A能生成一分子环状化合物E,则E为
