Q. 6.55 - An Introduction to General, Organic, and Biological Chemistry

Question

Name each of the following ionic or molecular compounds: 

(a) $Al{\left(S{O}_4\right)}_3$, antiperspirant

(b) $CaC{O}_3$, antacid

(c) $N_{2}O$, "laughing gas," inhaled anesthetic

(d) $Mg{\left(OH\right)}_2$, laxative

Step-by-Step Solution

Answer

(a) The name of the compound is Aluminum sulphate.

(b) The name of the compound is Calcium carbonate.

(c) The name of the compound is Nitrous oxide.

(d) The name of the compound is Magnesium hydroxide.

Part (a) Step 1: Given Information

We have to find out the name of the compound $A{l}_2{\left(S{O}_4\right)}_3$.

Part (a) Step 2: Explanation

As in $A{l}_2{\left(S{O}_4\right)}_3$,

 $A{l}^{+3}$ and $S{O_4}^{-2}$ molecules are present So, it is an ionic compound and Al is Aluminum and $S{O}_4$ is sulphate.

Hence, the name of compound is Aluminum sulphate.

Part (b) Step 1: Given Information

We have to find out the name of the compound $CaC{O}_3$.

Part (b) Step 2: Explanation

As in $CaC{O}_3$,

$C{a}^{+2} and C{O_3}^{-2}$molecules are present which shows that it is an ionic compound and Ca is Calcium and $C{O_3}^{-2}$is carbonate.

Hence, the name of the compound is Calcium carbonate.

Part (c) Step 1: Given Information

We have to find out the name of the compound $N_{2}O$.

Part (c) Step 2: Explanation

As in $N_{2}O$,

N and O two non-metals are present which shows that this is molecular compound where N is Nitrogen and O is Oxygen.

Hence, the name of this compound is Nitrous Oxide.

Part (d) Step 1: Given Information

We have to find out the name of the compound $Mg{\left(OH\right)}_2$.

Part (d) Step 2: Explanation

As in $Mg{\left(OH\right)}_2$,

$M{g}^{+2} and O{H}^{-}$ molecules are present which states that it is an ionic compound where Mg is Magnesium and OH is hydroxide.

Hence, the name of this compound is Magnesium Hydroxide.
