Please answer correctly! And as fast as possible.
Please also indicate what carbon is what by writing the shift beside it look at the example.
Note: the degree of unsaturation is 2 (i.e. the structures should contain 2 double bonds or a triple bond or a ring and a double bond etc.)
An example for C5H10O:
By accessing the information contained in the tables below, obtain the correct chemical structure for each condition (#1-4), assuming they all share the molecular formula CHO. DEPT-135 Data Condition 1 12.6(-), 13.9(+), 55.1(-), 79.6(NP), 87.8(NP) Condition 2 42.9(-), 71.2(+), 127.9(+) Condition 3 31.8(+), 69.4(NP), 72.1(+), 88.3(NP) Condition 4 9.8(-), 21.1(+), 27.5(+), 208.1(NP) NOTE: NP stands for "NO PEAK" Hint: Condition 4 exhibits a carbonyl peak, along with some small peaks close to 3000 cm- in the range >3000 cm-1
