WebOct 13, 2010 · The “flavor” of each bond depends on the relative proportions of s orbital and p orbital content: sp 3 = 25% s character, 75% p character; sp 2 = 33% s character, 66% p character; sp = 50% s character, 50% p character. It is these hybrid orbitals that form sigma bonds (σ bonds). Sigma bonds are created from the head-on overlap of WebA Pi bond is a covalent bond which is formed by the side-to-side overlap of two atomic orbitals. The atomic orbital combinations can be p x -p x or p y -p y. Similar to the sigma bonding, a pi bond can be bonding or antibonding. Sigma bonds are relatively stronger when compared with pi bonds. Hence, pi bonds are easily broken while sigma bonds ... cycloplegics and mydriatics
