Q. 4.5 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the names for the elements in each of the following formulas of compounds used in medicine :

a. table salt, $\mathrm{NaCl}$

b. plaster casts, ${\mathrm{CaSO}}_4$

c. Demerol, ${\mathrm{C}}_{15}{\mathrm{H}}_{22}{\mathrm{ClNO}}_2$

d. treatment of bipolar disorder, ${\mathrm{Li}}_2{\mathrm{CO}}_3$

Step-by-Step Solution

Answer

a. The elements in the compound are Sodium and Chlorine.

b. The elements in the compound are Calcium, Sulphur and Oxygen.

c. The elements in the compound are Carbon, Hydrogen, Chlorine, Nitrogen and Oxygen.

d. The elements in the compound are Lithium, Carbon and Oxygen.

Part (a) Step 1 : Given information

We have to write down the names of the elements present in table salt compound.

Part (a) Step 2 : Simplification

We know that,

In $\mathrm{NaCl}$ table salt. $\mathrm{Na}$ is Sodium and $\mathrm{Cl}$ is chlorine

So, elements present in table salt are sodium and chlorine.

Part (b) Step 1 : Given information

We have to write down the names of the elements present in Plaster casts compound.

Part (b) Step 2 : Simplification

We know that,

In ${\mathrm{CaSO}}_4$ plaster casts, $\mathrm{Ca}$ is Calcium, $\mathrm{S}$ is sulfur and $\mathrm{O}$ is oxygen

So the elements present in plaster casts are Calcium, sulfur and oxygen.

Part (c) Step 1 : Given information

We have to write down the names of the elements present in Demerol compound.

Part (c) Step 2 : Simplification

We know that,

In ${\mathrm{C}}_{15}{\mathrm{H}}_{22}{\mathrm{ClNO}}_2$ demerol, $\mathrm{C}$ is carbon, $\mathrm{H}$ is hydrogen, $\mathrm{Cl}$ is chlorine, $\mathrm{N}$ is nitrogen and $\mathrm{O}$ is oxygen

So the elements present in demerol compound are carbon , Hydrogen , chlorine , Nitrogen and Oxygen.

Part (d) Step 1 : Given information

We have to write down the names of the elements present in treatment of bipolar disorder compound.

Part (d) Step 2 : Simplification

We know that, 

In ${\mathrm{Li}}_2{\mathrm{CO}}_3$ treatment of bipolar disorder, $\mathrm{Li}$ is Lithium, $\mathrm{C}$ is carbon and $\mathrm{O}$ is oxygen.

So the elements present in treatment of bipolar disorder is Lithium, Carbon and Oxygen.
