2. name the following compounds.\na. cui\nb. feo\nc. zn(clo₃)₂\nd. pcl₅\ne. ca(hco₃)₂\nf. cl₄\ng. pbr₃

Answer

Explanation:

Step1: Identify cation and anion for ionic compounds

For ionic compounds, name the cation first and then the anion. For transition - metals, indicate the oxidation state in Roman numerals.

Step2: Name binary molecular compounds

For binary molecular compounds, use prefixes to indicate the number of atoms of each element.

a. CuI

Copper(I) iodide. Copper is a transition - metal with a + 1 oxidation state here and iodide is the anion.

b. FeO

Iron(II) oxide. Iron is a transition - metal with a + 2 oxidation state here and oxide is the anion.

c. Zn(ClO₃)₂

Zinc chlorate. Zinc is the cation and chlorate ($ClO_3^-$) is the poly - atomic anion.

d. PCl₅

Phosphorus pentachloride. It is a binary molecular compound. The prefix "penta -" is used for 5 chlorine atoms.

e. Ca(HCO₃)₂

Calcium hydrogen carbonate or calcium bicarbonate. Calcium is the cation and hydrogen carbonate ($HCO_3^-$) is the poly - atomic anion.

f. CCl₄

Carbon tetrachloride. It is a binary molecular compound. The prefix "tetra -" is used for 4 chlorine atoms.

g. PBr₃

Phosphorus tribromide. It is a binary molecular compound. The prefix "tri -" is used for 3 bromine atoms.

Answer:

a. Copper(I) iodide b. Iron(II) oxide c. Zinc chlorate d. Phosphorus pentachloride e. Calcium hydrogen carbonate (or calcium bicarbonate) f. Carbon tetrachloride g. Phosphorus tribromide
