Studdy Solution

STEP 1

Assumptions1. We are looking for anionic compound. . Anionic compound is formed by the complete transfer of electrons from a metal to a non-metal and the resulting ions have achieved an octet configuration.
3. The given options are None of these, CO\mathrm{CO}_{}, 3\mathrm{}_{3}, Fe3\mathrm{Fe}_{} \mathrm{}_{3}, H\mathrm{H}_{} \mathrm{}.

STEP 2

We need to identify which of the given options is anionic compound. We can do this by checking if the compound is formed by the complete transfer of electrons from a metal to a non-metal.

STEP 3

Check the first option, CO2\mathrm{CO}_{2}.
Carbon dioxide (CO2\mathrm{CO}_{2}) is a molecular compound, not anionic compound. It is formed by the sharing of electrons between carbon and oxygen atoms, not by the complete transfer of electrons.

STEP 4

Check the second option, 3\mathrm{}_{3}.
ulfur trioxide (3\mathrm{}_{3}) is a molecular compound, not anionic compound. It is formed by the sharing of electrons between sulfur and oxygen atoms, not by the complete transfer of electrons.

STEP 5

Check the third option, Fe23\mathrm{Fe}_{2} \mathrm{}_{3}.
Iron(III) oxide (Fe23\mathrm{Fe}_{2} \mathrm{}_{3}) is anionic compound. It is formed by the complete transfer of electrons from iron (a metal) to oxygen (a non-metal).

STEP 6

Check the fourth option, H2\mathrm{H}_{2} \mathrm{}.
Water (H2\mathrm{H}_{2} \mathrm{}) is a molecular compound, not anionic compound. It is formed by the sharing of electrons between hydrogen and oxygen atoms, not by the complete transfer of electrons.
Theionic compound among the given options is Fe23\mathrm{Fe}_{2} \mathrm{}_{3}.
