Question

The amino and carboxyl functional groups tend to form bases and acids by attracting or droppingA) an electron.B) a neutron.C) a proton and an electron.D) a neutron and a proton

Answer 1

Explanation:

When a substance or chemical specie accepts a proton then an acid is formed. Whereas is a substance or chemical specie tends to lose a proton then a base is formed.

Chemical formula of amino group is $-NH_{2}$ and it is able to lose a proton to form R-NH-R'. When it tends to gain a proton the it form R-NH_{3} compound.

Chemical formula of carboxylic group is -COOH. When it loses a proton it forms $-COO^{-}$ ion and whenit gains an electron then it forms $-O-C-OH_{2}$.

Therefore, we can conclude that the amino and carboxyl functional groups tend to form bases and acids by attracting or dropping a proton.
