Question

Which of the following molecule can form a zwitter ion?

विकल्प

• CCl₃NO₂

• CH₃CH₂NH₂

• CH₃COOH

• NH₂CH₂COOH

Answer 1

NH₂CH₂COOH

Explanation:

Zwitter ions are those that can act as both acids and bases. NH₂CH₂COOH generates the zwitter ion ⁺H₃NCH₂COO⁻ in aqueous solution, which acts as a base due to the presence of the COO⁻ group and as an acid due to the presence of the \[\ce{NH^+_3}\] group.
