A) \[{{(C{{H}_{3}})}_{2}}CHCHO\]
B) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}CHO\]
C) \[C{{H}_{3}}C{{H}_{2}}CHBrCHO\]
D) \[C{{H}_{3}}C{{H}_{2}}CB{{r}_{2}}CHO\]
Correct Answer: C
Solution :
[c] An optically active compound contains a chiral carbon atom. [a] \[\begin{align} & {{H}_{3}}C-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-CHO \\ & (no\,\,chiral\,\,carbon\,\,atom) \\ \end{align}\] [b] \[\begin{align} & H-\underset{H}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,=O \\ & (no\,\,chiral\,\,carbon\,\,atom) \\ \end{align}\] [c] \[\begin{align} & H-\underset{{}}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{\underset{Br}{\mathop{\underset{|}{\mathop{^{*}C}}\,}}\,}}\,}}\,-\underset{\underset{O}{\mathop{\parallel }}\,}{\mathop{C}}\,}}\,-H \\ & (contains\,\,chiral\,\,carbon\,\,atom) \\ \end{align}\] [d] \[\begin{align} & H-\underset{{}}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\overset{H}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-\underset{Br}{\mathop{\underset{|}{\mathop{\overset{Br}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-}}\,\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,=O \\ & (no\,\,chiral\,\,carbon\,\,atom) \\ \end{align}\]
