Question

Which of the following are secondary bromides?

(i) \[\ce{(CH3)2 CHBr}\]

(ii) \[\ce{(CH3)3C CH2Br}\]

(iii) \[\ce{CH3CH(Br)CH2CH3}\]

(iv) \[\ce{(CH3)2 CBrCH2CH3}\]

Answer 1

(i) \[\ce{(CH3)2 CHBr}\]

(iii) \[\ce{CH3CH(Br)CH2CH3}\]

Explanation:

\[\begin{array}{cc} 
\ce{CH3 - CH - Br and  CH3CHCH2CH3}\\
\phantom{.}|\phantom{.................}|\phantom{....}\\
\phantom{.}\ce{CH3}\phantom{..............}\ce{Br}\phantom{...}
\end{array}\]

are secondary bromides.
