The names of all binary compounds, both ionic and molecular, end in the letters a. -ade b. -ite c. -ide d. -ate

Answer : The correct option is, (B) -ide

Explanation :

Binary ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.

The rules for naming of binary molecular compound :

In the given formula, the lower group number element is written first in the name and keep its element name and the higher group number is written second.

Gets a prefix if there is a subscript on it such as mono for 1, di for 2, tri for 3 and so on.

Use the root of the element name, if it is an anion then use suffix (-ide).

Always use a prefix on the second element such as mono for 1, di for 2, tri for 3 and so on.

Therefore, the names of all binary compounds, both ionic and molecular, end in the letters, -ide.
