A) \[\text{II,III,V,I,IV}\]
B) \[\text{V,II,I,IV,III}\]
C) \[\text{III,IV,I,II,V}\]
D) \[\text{II,V,I,IV,III}\]
Correct Answer: A
Solution :
(i) \[-\underset{N}{\mathop{\underset{|}{\mathop{\overset{N}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\underset{C}{\mathop{\overset{C}{\mathop{\underset{|}{\mathop{\overset{|}{\mathop{N}}\,}}\,}}\,}}\,,\] (ii) \[-\underset{Br}{\mathop{\underset{|}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{3}},\] (iii) \[-\underset{O}{\mathop{\underset{|}{\mathop{\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\underset{C}{\mathop{\underset{|}{\mathop{O}}\,}}\,,\] (iv) \[-\underset{H}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-\underset{O}{\mathop{\underset{|}{\mathop{\overset{O-C}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OC{{H}_{3}},\] (v) \[-\overset{O\,}{\mathop{\overset{|}{\mathop{\underset{H}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,\overset{-}{\mathop{-}}\,\overset{C}{\mathop{\overset{|}{\mathop{O}}\,}}\,\] Arrange \[(NNN),\,\,(BrCC),\,\,(OOO),\,(CHH),\,\,(OOH)\] in increasing atomic number. The order is ii, iii, v, i, iv.
