21 Fragmentation patterns can be helpful in distinguishing constitutional isomers.The many isomers of C11H140 include compounds with an aromatic ring and acarbonyl group.One isomer has a strong IR absorption peak at 1700 cm¯1.The mass spectrum shows the molecular ion M at m/z = 162, while the base peakoccurs at m/z = 147. Another significant peak is seen at m/z = 43.Which structure is most consistent with this data?A) IB) IIC) IIIVD) IV

Propylbenzene, C6H5CH2CH2CH3, and isopropyl benzene, C6H5CH(CH3)2, are constitutional isomers with the molecular formula C9H12. One of these compounds shows prominent peaks in its mass spectrum at m/z 120 and 105. The other shows prominent peaks at m/z 120 and 91. Which compound has which spectrum?
A graduate student was following a procedure to make 3-propylcyclohexa-1,4-diene. He overheated the product. He isolated the product, which gave the appropriate =C−H stretch in the IR, but the C=C stretch appeared around 1630 cm−1as opposed to the literature value of 1650 cm−1for the desired product. The mass spectrum showed the correct molecular weight, but the base peak was at M–29 rather than at M–43 as expected. Because of the anomalous IR spectrum, he took a UV spectrum that showed λmaxat 261 nm. c) Draw the structure of the desired product and propose a structure for the actual product d) Show why he expected the MS base peak to be at M–43, and show how your proposed structure would give an intense peak at M–2
