Take The Covalent Bonding Practice Quiz!
What do you know about covalent bonds? Covalent bonds are essential ways of bonding in organic chemistry, and the creation of covalent bonds is the result of atoms sharing some electrons. Examples of common covalent bonds include peptide and disulfide bonds between amino acids. There are two kinds of covalent bonds: non-polar and polar, and these are relatively strong bonds. This quiz will demonstrate your knowledge of covalent bonding.
