Detailed explanation-1: -Sigma bonds are the strongest covalent chemical bonds. Sigma bonds also occur when an s and a p orbital share a pair of electrons or when two p orbitals that are parallel to the internuclear axis share a pair of electrons (see Figure 3-4).
Detailed explanation-2: -The sharing of electrons causes the nuclei of the atoms to be attracted toward the shared electron pair, which results in a strong bond (strong bonds = harder to break). From strongest to weakest: Triple covalent bonds, double covalent bonds, single covalent bonds.
Detailed explanation-3: -Because of the close sharing of pairs of electrons (one electron from each of two atoms), covalent bonds are stronger than ionic bonds.
Detailed explanation-4: -Answer and Explanation: The three types of chemical bonds in order of weakest to strongest are as follows: ionic bonds, polar covalent bonds, and covalent bonds. These types of bonds are determined by the difference in electronegativity between the bonded atoms.
