The NO2 group directs meta with-deactivation in electrophilic aromatic substitution. The nitroso group - NO directs ortho-para with - deactivation. Write out the electroinc structures of - NO2 and -NO and explain the differences in behavior. Show all pertinent resonance forms for the addition of...
can anybody help me to answer this question?
Comoplete hydrogenation of 1,3,5,7-cyclooctatetraene is exothermic by -101 kcal/mole. Hydrogenation of cyclooctene proceeds with delta H equal to -23kcal/mol. On the basis of these data, would you call cyclooctatetraene armotic? Justify your anser...
