What are Epididymitis and Orchitis? Pain in the scrotum or testicle (âtesteâ) might be from epididymitis, orchitis or both. Epididymitis is swelling or pain in the back of the testicle in the coiled tube (epididymis) that stores and carries sperm.
Share. By Anne Marie Helmenstine, Ph.D. Definition: Valence bond theory is a chemical bonding theory that explains the bonding between two atoms is caused by the overlap of half-filled atomic orbitals. The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.
Select the correct statement about pi-bonds in valence bond theory. A) A sigma bond is stronger than a pi bond. B) A pi bond can hold 4 electrons, two above and two below the Ï-bond (sigma) axis. C) A carbon-carbon double bond consists of two Ï (pi) bonds. D) A Ï bond is the same strength as a Ï... show more Select the correct statement about pi-bonds in valence bond theory. A sigma bond is stronger than a pi bond. B) A pi bond can hold 4 electrons, two above and two below the Ï-bond (sigma) axis. C) A carbon-carbon double bond consists of two Ï (pi) bonds. D) A Ï bond is the same strength as a Ï bond. E) A Ï bond between two carbon atoms restricts rotation about the CâC axis.
