6. Question & Answer
  • Bromobenzene is a complete compound, bromophenyl is a description of a unit in a larger compound Chemists abbreviate some groups to simplify the names of more complex compounds. So while bromobenzene is a complete name for a compound, bromophenyl signals that the unit occurs as part of a larger com...
  • I was solving some reactivity problems, and I was asked to prepare toluene from bromobenzene. While the suggested solution of the problem involves the preparation of a Grignard reagent, followed by a reaction with methyl bromide, I was wondering: Could the same compound be prepared with the straigh...
  • Benzene is 45 kJ/mol more energetic than bromobenzene. I understand that due to resonance in bromine to benzene in bromobenzene increase the stability but such an enormous amount of energy can't only be dealt by resonance. There must be another reason. What is it?
