Question

Which one of the following is not having two chiral centres? (A)  H3CCH(Br)CH(OH)CH3  (B)  H3CCH(NH2)CH(Br)CH3  (C)  H3CCH(NH2)CH(Cl)CH3  (D)  H3CCH(NH2)CH2CH3

The carbon all the four valencies of which are satisfied by four different groups is called chiral carbon or chiral centre. In H3C- overset text* mathopC HCH2CH3 only one chiral centre is found ( overset* mathopC = chiral carbon atom).

Q. Which one of the following is not having two chiral centres?

$H_{3} CC H (B r) C H (O H) C H_{3}$

$H_{3} CC H (N H_{2}) C H (B r) C H_{3}$

$H_{3} CC H (N H_{2}) C H (Cl) C H_{3}$

$H_{3} CC H (N H_{2}) C H_{2} C H_{3}$

The carbon all the four valencies of which are satisfied by four different groups is called chiral carbon or chiral centre. In $H_{3} C - C * H C H_{2} C H_{3}$ only one chiral centre is found ( $C * =$ chiral carbon atom).
