TWISTING JELLY BEANS

Hold two toothpicks side by side and attach onejelly bean to each end such that each jelly bean has both toothpicks poked into it. As before, hold one jelly bean while rotating the other. What kind of rotations are possi blenow  

The structures for three odoriferous organic compounds containing One or more benzene rings toluene, naphthalene, and l,4-dichloroben2enc. 

Prolonged exposure to benzene has been found to increase the risk of developing certain cancers.The structure of aspirin contains a benzene ring. 

Does this necessarily mean that prolonged exposure to aspirin will increase a person s risk of developing can cer  

Was this youT answer No. Although benzene and aspirin both contain a benzene ring, these two molecules have different overall structures, which means the properties of one are quite different from the properties of the other. Each carbon-containing organic compound has its own set of unique physical, chemical, and biological properties. While benzene may cause cancer, aspirin is a safe remedy for headaches. 

Two carbon atoms connected by a single bond can rotate relative to each other. As we discussed in Section 12.1, this ability to rotate can give rise to numerous conformations (spatial orientations) of an organic molecule. Is it also possible for carbon atoms connected by a double bond to rotate relative to each other Perform this quick activity to see for yourself.

Carbon—carbon single bonds can rotate but carbon-carbon double bonds cannot rotate (see Hands-On Chemistry Twisting Jelly Beans ). How many different structures are shown here ...
