WebWhat is the molecular formula of benzene? C₆H₆ Phenyl group C₆H₅ What is the Kekule model for benzene? - planar ring of carbon with alternating C=C and C-C between them - each C-atom bonded to one H-atom If Kekule's model was correct, what would you expect of the length of the C-C and C=C bonds? Is this true? WebThe bromination of benzene is an example of an electrophilic aromatic substitution reaction. In this reaction, the electrophile (bromine) forms a sigma bond to the benzene ring, yielding an intermediate. Then, a proton is removed from the intermediate to form a substituted benzene ring. Created by Sal Khan. Sort by: Top Voted Questions WebThe old name for the alkanes was the paraffins. ? Alkynes may have one or more triple bonds in their structure. ? Alkanes are much more stable than alkenes because of the presence of the C=C double bond. ? The simplest aromatic compound is benzene.
