Detailed explanation-1: -A zwitterion is an ion that contains two functional groups. In simple terms, it is an ion possessing both positive and negative electrical charges. Therefore, zwitterions are mostly electrically neutral (the net formal charge is usually zero).
Detailed explanation-2: -A zwitterion is a molecule that has both positive and negative charges. It is made up of two (or more) functional groups. One of its components has a positive charge and another one with a negative charge. Because of this, the net charge of a zwitterion is zero.
Detailed explanation-3: -Zwitterions contain both positive-and negative-charged groups, with an overall neutral charge.
Detailed explanation-4: -What Are Zwitterions? Zwitterions, sometimes called dipolar ions are molecules with an equal number of positive and negative charges. Therefore, though the molecules themselves are ions, their net charge is zero.
Detailed explanation-5: -So, the correct answer is ‘Zwitterionic form’.
