A) 2 - chloropropanal
B) 2 - chlorobutane
C) 2 - chloropentane
D) 2 - chloro - 2- methylbutane
Correct Answer: D
Solution :
[d] The optically inactive compound must contains achiral carbon atom(s). Option [d] contains achiral carbon atom \[\underset{2-chloropropanol}{\mathop{C{{H}_{3}}-\underset{H}{\overset{Cl}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-CHO}}\,\] \[\underset{2-\text{chlorobutane}\,\,\,\,\,\text{(chiral)}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\underset{H}{\mathop{\overset{Cl}{\mathop{\underset{|}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}}}}\,\] \[\underset{2-\text{chloropentane}\,\,\text{(chiral)}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-\underset{H}{\mathop{\overset{Cl}{\mathop{\underset{|}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}}}}\,\] \[\underset{2-\text{chloro}-2-\text{methylbutane}\,\,\,\text{(achira)}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\underset{Cl}{\mathop{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}}}}\,\]
