Which of the following compounds is ionic but yet it is expected to
contain covalent bonds as well in the form of a polyatomic ion?

NH3

KBr

CO2

NaF

Fe(NO2)3

Answer 1

Answer:

Fe(NO2)3

Explanation:

A poly atomic ion is an ion that contains more than one atom.

If we look at all the compounds that have been mentioned among the options; KBr and NaF are both ionic but do not contain any covalent poly atomic ion.

However, Fe(NO2)3  contains NO2^+ which is a poly atomic ion that contains the covalent bond.
