(a) $A{l}_2{\left(C{O}_3\right)}_3$ (b) $CI{F}_5$ (c) $BC{l}_3$ (d) $M{g}_3{N}_2$ (e) $CI{O}_2$ (f) $CrP{O}_4$

Step-by-Step Solution

Answer

(a) $A{l}_2{\left(C{O}_3\right)}_3$ is Ionic compound and  the name of this compound is Aluminum carbonate.

(b) $CI{F}_5$ is molecular compound and the name of this compound is Chlorine pentafluoride.

(c) $BC{l}_3$ is molecular compound and the name of this compound is Boron trichloride.

(d) $M{g}_3{N}_2$is Ionic compound and the name of this compound is Magnesium nitride.

(e) $Cl{O}_2$ is molecular compound and the name of this compound is  Chlorine dioxide.

(f) $CrP{O}_4$is ionic compound and the name of this compound is Chromium Phosphate..

Part(a) Step 1: Given information

We have been given,

Al, C and O symbols are used in this formula.

Part(a) Step 2: Explanation

Now, $A{l}_2{\left(C{O}_3\right)}_3$is Ionic compound, This is because the ionic combination contains three carbonate ions for every two Aluminium ions.

As there are $2$molecule of Aluminium and $3$molecule of Carbon and  $9$ molecule of Oxygen,

The name of this compound is Aluminum carbonate. 

Part(b) Step 1: Given information

We have been given,

Cl and F symbols used in this formula.

Part(b) Step 2: Explanation

Now, $Cl{F}_5$ is molecular compound Because both elements are nonmetals,

As there are $1$molecule of Chlorine and $5$molecule of fluorine,

Then the name of given compound is Chlorine pentafluoride. 

Part(c) Step 1: Given information

We have been given,

B and Cl symbols are used in this formula. 

Part(c) Step 2: Explanation

Now,  $BC{l}_3$is molecular compound Because both elements are nonmetals,

As there are $1$ molecule of Boron and $3$molecule of Chlorine,

Then the name of given compound is Boron trichloride.

Part(d) Step 1: Given information

We have been given,

Mg and N symbol are used in this formula.

Part(d) Step 2: Explanation

Now, $M{g}_3{N}_2$is ionic compound, A chemical bond is a long-term attraction between atoms, ions, or molecules that allows chemical compounds to form.

As there are $3$molecule of magnesium and $2$molecule is nitrogen.

Then the name of given compound is  Magnesium nitride. 

Part(e) Step 1: Given information

We have been given,

Cl and O symbols are used in this formula.

Part(e) Step 2: Explanation

Now, $Cl{O}_2$ is molecular compound Because both elements are nonmetals,

As there are $1$molecule chlorine and $2$molecule of Oxygen,

Then the name of this given compound is Chlorine dioxide. 

Part(f) Step 1: Given information

We have been given,

Cr, P and O symbols are used in this formula.

Part(f) Step 2: Explanation

Now, $CrP{O}_4$ is ionic compound and A chemical bond is a long-term attraction between atoms, ions, or molecules that allows chemical compounds to form.

As there are $1$molecule of  chromium and $1$molecule of Phosphorus and $4$molecule of oxygen,

Then the name of given compound is Chromium Phosphate..
