A) 1-chloropentane
B) 2-chloropentane
C) 1-chloro-2-methyl pentane
D) 3-chloro-2-methyl pentane
Correct Answer: A
Solution :
Chiral carbon has all the four different groups attached to it. (a)\[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}Cl\]no chiral caii/on atom (b)\[C{{H}_{3}}\underset{\begin{smallmatrix} | \\ Cl \end{smallmatrix}}{\overset{*}{\mathop{CH}}}\,C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}\]one chiral carbon atom (c)\[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{*}{\mathop{CH}}}\,C{{H}_{2}}Cl\]one chiral carbon atom (d)\[C{{H}_{3}}\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{*}{\mathop{CH}}}\,-\underset{\begin{smallmatrix} | \\ Cl \end{smallmatrix}}{\overset{*}{\mathop{CH}}}\,C{{H}_{2}}C{{H}_{3}}\]two chiral carbon atom
