Answer: They are often amines.
Explanation:
Covalent bases are lewis bases which can donate lone pair of electrons. Amines contain [tex]NH_2[/tex] as the functional group and the lone pair on nitrogen can easily be shared.
[tex]RNH_2+H^+\rightarrow RNH_3^+[/tex]
a) The bases which gives hydroxide ions in water are ionic bases as they are formed by complete transference of electrons. Example: [tex]Mg(OH)_2[/tex]
[tex]Mg(OH)_2\rightarrow Mg^{2+}+2OH^-[/tex]
b) The substance which produce hydrogen ions are ionic acids. Example: [tex]HCl[/tex]
[tex]HCl\rightarrow H^{+}+Cl^-[/tex]
d) Covalent compounds are named differently than ionic compounds.
