How many electrons are there in benzene to form delocalized electronic cloud
Correct answer: C. Six
- A. Three
- B. Four
- C. Six
- D. Eight
Explanation
Benzene is a planar molecule with a hexagonal ring of carbon atoms and alternating double bonds. The delocalized electron model in benzene involves the six pi electrons from the double bonds forming a delocalized electron cloud above and below the carbon atom plane, creating aromaticity. Options A and B are incorrect as they do not provide enough pi electrons for the cloud. Option D is incorrect as it suggests additional pi bonds beyond what is needed for benzene's aromaticity.
