Which among the following statements are true for glycine? 1 . It exists in crsytalline form 2 . It is optically active 3 . It is soluble in water 4 . It can form Zwitter ions

Options

  1. A1, 2 and 3
  2. B1, 2 and 4
  3. C1, 3 and 4
  4. D2, 3 and 4

Correct answer

C. 1, 3 and 4

Step-by-step solution

It is ionic, so it exists in cyrstalline form because it is ionic, so it is soluble in water. Because acidic and basic groups are present in the same molecule, so internal salt formation occurs to form dipolar ion H 3 N + - C H 2 C O O - .
