Benzene consists of 6 carbon and 6 hydrogen atoms where the central atom usually is hybridized. Our videos will help you understand concepts, solve your homework, and do great on your exams. This arrangement results from sp 2 hybridization, the mixing of one s orbital and two p orbitals to produce three identical hybrid orbitals oriented in a trigonal planar geometry (). Median response time is 34 minutes and may be longer for new subjects. Sp2c. We will look at the details below. I think? How many sigma bonds and pi bonds are there in each of the following: CH2Cl2 C2H3Cl C5H6 C6N4 .
