That would be an amino acid. The
and -COOH is the functional group for a carboxylic acid hence AMINO ACID.
For a neutral atom, the number of positive protons is equal to the number of negative electrons and the charge is zero.
For this question, we see that the number of protons exceeds the number of electrons by 2, which means that this ion in a positively charged charged ion with charge of +2.

Explanation:
Necessary precautions are required to be taken in the laboratory when Benzophenone reacts with phenylmagnesiumbromide in ether solution to produce Triphenylmethanol. Such precautions include proper drying of any glasswares used as well as the use of tight sealing glasswares during this experiment to ensure that the Grignard reaction is free of any traces of water or moisture. Any presence of moisture during the reaction would result in a decrease in the yield of triphenylmethanol produced thereby resulting in the decrease of the effectiveness of the Grignard reaction.
