33 sigma bonds and 4 pi bonds

Quizplus · Accepted Answer

The correct answer is that ibuprofen contains 35 sigma bonds and 4 pi bonds. This is because each single bond, double bond, or triple bond counts as one sigma bond, and each double bond also has one pi bond. The ibuprofen molecule contains 11 single sigma bonds, 4 double sigma bonds, and 20 single sigma bonds involved in ring structures, for a total of 35 sigma bonds. It also contains 4 pi bonds from the double bonds in the ring structures. Therefore, the statement that it has 33 sigma bonds and 4 pi bonds is false.
