Concept explainers
(a)
Interpretation:
The major product obtained on treating the compounds in problem 29 with Br2 at 125°C should be identified.
Concept introduction:
Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.
Bond strength is depends on the formation of the radical, if the radical is involving in resonance which is weakest bond strength.
Bromination:
1-Methyl cyclohexane is undergoes radical bromination which forms 1-bromo-1-methyl cyclohexane therefore, bromination will occur where the tertiary radical is present. Because bromination will occur selectively in tertiary alkyl radical. (bromination reactions are more selective reaction)

- Consider this step in a radical reaction: Br N O hv What type of step is this? Check all that apply. Draw the products of the step on the right-hand side of the drawing area below. If more than one set of products is possible, draw any set. Also, draw the mechanism arrows on the left-hand side of the drawing area to show how this happens. O primary Otermination O initialization O electrophilic O none of the above × ☑arrow_forwardNonearrow_forwardCan I get a drawing of what is happening with the orbitals (particularly the p orbital) on the O in the OH group? Is the p orbital on the O involved in the ring resonance? Why or why not?arrow_forward
