（1）写出甲苯制TNT的化学方程式 ____

（2）某烷烃A的蒸气的密度是相同状况下氧气密度的4倍，经测定得知该分子中共含有6个甲基．

①若A不可能是烯烃与氢气的加成产物，则A的结构简式为 ____；

②若A是炔烃与氢气的加成产物，则A的结构简式为　 ____　．

（3）①某烃1mol与2molHCl完全加成，生成的氯代烷最多可以与4molCl₂发生光取代反应，则该烃的结构简式为　 ____　；

②已知烯烃在氧化剂作用下，可按下式断裂其双键

分子式为C₁₀H₁₈的有机物A催化加氢后得化合物B，其分子式为C₁₀H₂₂，化合物A跟过量的酸性高锰酸钾作用可以得到三种化合物：

由此判断A的结构简式为 ____

    A man lived in a village. ____. The cat couldn't run fast, and she couldn't bite, because she was so old. One day, when she saw a mouse, she jumped and caught it. ____. The mouse got out of her mouth and ran away.
