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.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
