Chapter 4, Problem 19A

Interpretation Introduction

Interpretation:

The formulas and names of polyatomic anions of carbon are to be listed.

Concept introduction:

Polyatomic ion involves more than one atom which carries a net charge and exists as a single unit. For example: sulphate ion $(S{O}_4{}^{2-})$ , Phosphate ion $(P{O}_4{}^{3-})$ .

Explanation of Solution

Polyatomic ions containing carbon are cyanide ion, carbonate ion, acetate ion and oxalate ion.

Name	Formula
Carbonate	$C{O}_3{}^{2-}$
Acetate	$C{H}_{3}CO{O}^{-}$
Oxalate	$C_2{O}_4{}^{2-}$
cyanide	$C{N}^{-}$
