The major monobrominated product which results when ethylcyclohexane is treated with Bromine in the presence of sunlight bromomethane a tertiary alkyl bromide a secondary alkyl bromide a primary alkyl Bromide Identify the major product when the following compound (2-methyl2-pentene) is heated with NBS (Hint: Consider resongance of the free radical formed) \[ \left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}=\mathrm{CHCH}_{2} \mathrm{CH}_{3} \] \[ \begin{array}{l} \left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}(\mathrm{Br}) \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_{2} \mathrm{CH}_{3} \\ \left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}(\mathrm{Br}) \mathrm{CH}=\mathrm{CHCH}_{3} \end{array} \] \[ \left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}(\mathrm{Br})-\mathrm{CHCH}_{2} \mathrm{CH}_{3} \] \[ \left(\mathrm{CH}_{3}\right)_{2} \mathrm{C}=\mathrm{CHCH}(\mathrm{Br}) \mathrm{CH}_{3} \]
