Well, it turned out to be Cl2-CH-CH2-CH-Cl2. It was trickier than what I thought. But I have to say the my first solution also produces same spectrum and, in my mind based on the information given, there is no way to decide between the two.
Homework Statement
Draw the skeletal structure of the compound with molecular formulaC3H4Cl4 whose proton NMR spectrum contains a down-field triplet and an up-field triplet with relative integration of 2:2.
2. Rationale for Solution
Integration ratio of 2:2 means CH2-CH2, after this one carbon...
Sorry to hear about it. Didn't it give you the answer? Usually the program gives you the answer after your have exhausted your chances.
