One of the starting substances (ingredients) that is involved in a chemical reaction

Explanation:

In a chemical reaction, the starting substances are known as reactants and the ending substances are known as products.

When we write a chemical reaction equation then substances present on the left hand side of arrow are the reactants. Whereas the substances present on the right hand side of arrow are the products.

For example

Here, both A and B are the reactants whereas AB is the product.

Thus, we can conclude that one of the starting substances (ingredients) that is involved in a chemical reaction are reactants.

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.
