Question

What is Pentadivalent Bond?​

Answer 1

Answer:

it is "pentavalent bond". A carbon atom having five covalent bonds is referred to a pentavalent bond.

Answer 2

Pentavalent carbon (Texas carbon): A carbon atom with five covalent bonds. Sometimes called a Texas carbon because everything (including, apparently the valence of carbon) is "bigger in Texas". In most molecules carbon can have at most eight valence shell electrons, allowing for a maximum of four covalent bonds and/or lone pairs. Exceptions are very rare. In general pentavalent carbons are not acceptable in introductory organic chemistry.
