पर्याय
CH3C*HBrCH3
CH3C*HClCH2Br
HOCH2C*H(OH)CH2OH
CH3C*Br2CH3
उत्तर
CH3C*HClCH2Br
Explanation:
\[\begin{array}{cc}
\phantom{.......}\ce{CH2Br}\\
\phantom{..}|\\
\ce{CH3-C-Cl}\\
\phantom{..}|\\
\phantom{..}\ce{H}
\end{array}\]
A chiral centre is an atom that has four distinct groups linked to it in a way that prevents a superimposable mirror image.
