Question

Van der waals interactions result when hybrid orbitals overlap. a hydrogen atom loses an electron. molecules held by ionic bonds react with water. two polar covalent bonds react. electrons are not symmetrically distributed in a molecule.

Answer 1

Van der Waals interactions are weak attractions or interactions between molecules. They occur between polar, covalently bound atoms in different molecules. These bonds contribute to the three-dimensional structure of proteins.

Step-by-step explanation:

Van der Waals interactions are weak attractions or interactions between molecules. They occur between polar, covalently bound, atoms in different molecules. These weak attractions are caused by temporary partial charges formed when electrons move around a nucleus. Van der Waals attractions can occur between any two or more molecules and are dependent on slight fluctuations of the electron densities, which are not always symmetrical around an atom. For these attractions to happen, the molecules need to be very close to one another. These bonds, along with ionic, covalent, and hydrogen bonds, contribute to the three-dimensional structure of the proteins in our cells that is necessary for their proper function.

Answer 2

Van der waals interactions are the electrical interactions between two or more atoms and even molecules but the inter-molecular attractions between the molecules are not exactly strong, in fact they are the weakest. And these Van der waals interactions are happened when electrons are not symmetrical distributed in a molecule.
