There are three bonding pairs of electrons in BF3. There are 0 nonbinding pairs, but BF3 can accept two more electrons to give it a complete octet
Double and triple bonds are typically found in covalent bonding, where two atoms share two or three pairs of electrons, respectively. In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of ions. Thus, double and triple bonds are not typically present in ionic bonding.
Covalent compounds and molecular compounds are the same thing if I recalled correctly, just different terms of calling it. And covalent bonds are the bonds formed by the sharing of electrons between two atoms, and they are the strong forces of attraction WITHIN the molecule.Please do not get it mixed up with the weak van der Waals' forces that is found BETWEEN molecules and is caused by a temporary shift of electrons to one side of the molecule, resulting in a slightly positive/negative end.
The water molecule has a polar covalent bond.
hydrogen bonding between H2O and covalent bonding within the H2O molecule
The electrons in the outermost shell is called as valence electron. These electrons are free and they are involved in bonding reactions.
Covalent Bonding
valence electrons
Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
The "valence" electrons are responsible for chemical reactions and bonding. Valence electrons are found in the outer most orbital of the atom, farthest away from the nucleus.
The electrons in the valence shell are those most concerned with bonding and how that occurs. The "non-bonding" electrons are the ones in the inner shells, or the non-valence shells of an atom. Non-bonding electrons are also found in the valence shell. They are referred to as lone pairs. For example, in ammonia (NH3), nitrogen has one lone pair. In most circumstances, lone pair electrons do not form bonds (they do in a special type of covalent bond).

Methanol, CH3OH (CH4O) is a covalent molecular compound. It is liquid under normal conditions and there is hydrogen bonding between molecules
The water molecule has a polar covalent bond.
The lone pair electron region is the place around the central atom where electrons not bonding with another atom can be found. A lone pair of electrons are electrons that are not bonded with other atoms.
