A) a molecule with positive charge having one atom less
B) a molecule having both negative and positive charge on opposite ends.
C) a small molecule having only negative charge
D) a molecule having only positive charge on one of its atom
Correct Answer: B
Solution :
Zwitter ion is a molecule having both negative and positive charge on opposite ends. Acidic \[\overset{\text{Acidic}}{\mathop{\underset{\begin{smallmatrix} Basic \\ (Glycine) \end{smallmatrix}}{\mathop{C{{H}_{2}}\overset{O}{\mathop{\overset{|\,|}{\mathop{C}}\,}}\,.OH}}\,\rightleftharpoons \underset{\text{Zwitter}\,\text{ion}}{\mathop{\underset{^{\oplus }N{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,{{H}_{2}}\overset{O}{\mathop{\overset{|\,|}{\mathop{C}}\,}}\,{{O}^{\text{o}-}}}}\,}}\,\]
