Respuesta :
The orrect answer for above ststement is:
C. They are often amines
Amines ara covalent compounds and they coomomly are bases because they have lonley pair of electrons which can accept protons.
Explanation:
In the Lewis model, the H+ ion is the mobile species it receives a couple of electrons from the OH- ion to form a covalent bond. While the Lewis theory of acid-base reactions, bases distribute pairs of electrons and acids allow sets of electrons
The covalent bases are those which can donate lone pair of electrons
a) the compounds which can give hydroxide ions are ionic or bronsted lowry base
b) the compounds which can give hydrogen ions are acid
c) So the correct answer is they are often amine.
Amines have lone pair of electrons so they can donate electron and act as lewis base
d) they cannot be named as ionic compound
