describe the structure of Benzene - correct answers: • a cyclic hydrocarbon with 6 carbon, and 6 hydrogen atoms. 
• the bond angle and shape around each carbon is 120' trigonal planar. 
• each C has 4 outer shell electrons; 
 
- 3 of these bond to 2 other carbon atoms, and 1 to a hydrogen atom. - these form a Sigma bond. - a fourth outer shell electron in the 2p orbital is left behind above and below the planes of the carbon atoms.
