Select the best answer for the question.

The names of the compounds [tex][tex]$FeS, NaCl,$[/tex][/tex] and [tex][tex]$Al_2O_3$[/tex][/tex] all end in the suffix

A. -ide.

B. -ite.

C. -ate.

D. -ic.



Answer :

To determine the appropriate suffix for the given compounds, let’s take a close look at each one:

1. [tex]\( FeS \)[/tex]
- This compound is known as Iron(II) sulfide.

2. [tex]\( NaCl \)[/tex]
- This compound is known as Sodium chloride.

3. [tex]\( Al_2O_3 \)[/tex]
- This compound is known as Aluminum oxide.

By examining the names of these compounds:

1. Iron(II) sulfide ends with the suffix “-ide”.
2. Sodium chloride ends with the suffix “-ide”.
3. Aluminum oxide ends with the suffix “-ide”.

From this, we can see that all the compound names end with the suffix “-ide”.

Therefore, the best answer for the question is:

A. -ide
