i just learnt this recently but i need to look through my notes again.
An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.
A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.
1) P and I : Both non-metals with different electronegativities= Polar Covalent
2) Fe and O: Metal + non-metal = Ionic
3) S and Cl: Both non-metals with different electronegativities= Polar Covalent
4) S and S: Both non-metals and the same atoms = Non-polar Covalent
5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent
6) O and Cl: Both non-metals with different electronegativities= Polar Covalent
7) Be and Cl: Metal + non-metal = Ionic
8) Al and N: Metal + non-metal = Ionic

Water H₂O
<u>Step 2: Find Formulas Mass</u>
<em>Formula mass is molar mass.</em>
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
There are three other structural isomers of 1-butanol: 2-butanol (sec-butyl alcohol), 2-methyl-1-propanol (isobutyl alcohol), and 2-methyl-2-propanol (tert-butyl alcohol). 2-Butanol, or sec-butanol, or sec-butyl alcohol, or s-butyl alcohol, is a four-carbon chain, with the OH group on the second carbon.
Chemicals of this type: Ethanol
