polar covalent bonds
Q. What are secondary chemical bonds?
Secondary bonds are bonds of a different kind to the primary ones. They are weaker in nature and are broadly classified as Van der Waal’s forces and hydrogen bonds. These bonds are due to atomic or molecular dipoles, both permanent and temporary. For example, water molecule is made of one oxygen and two hydrogen atoms.

Q. What bonds are present in water?
A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
Q. Can HF bond with water?
The fairly positive hydrogen on one HF molecule will be attracted to one of these lone pairs on a nearby HF molecule. This is a hydrogen bond. Because the numbers are equal, each water molecule in the liquid could in principle form four hydrogen bonds, two using the δ+ hydrogens and two using the lone pairs.
Q. How many bonds are there in HF?
Fluorine gas consists of F2 molecules with a single F-F bond between atoms. Its hydrogen compound is hydrogen fluoride, HF, in which the F atom is surrounded by three lone pairs and one bonding pair (see right). The H-F bond is more polar than the H-O bond, being 41% ionic compared with 33%.
Q. What force is holding HOCl together?
dipole-dipole interactions
Q. What intermolecular force is the weakest *?
Intermolecular Forces : Example Question #10 Since the question asks us to order the compounds from least strength to greatest, we’ll start with the weakest IMF: Van der Waals forces, also called “induced dipoles” or London dispersion forces.
Q. Can CH2O form hydrogen bonds?
It doesnt form hydrogen bonds with other formaldehyde molecules but it can form them with molecules that do have a hydrogen atom bonded to O,N,F like water for example. No, but it will polymerize. A bottle of formalin (40% CH2O) kept in the fridge will form a white sludge of trioxane (3 CH2Os in a circle).
