25. Which bond forms from sideways overlap of p orbitals? a) Sigma (sigma ) bond b) Pi (pi ) bond c) Ionic bond d) Metallic bond

The correct answer is b) Pi $$(\pi )$$ bond.

A pi bond forms from the sideways overlap of p orbitals. In a covalent bond, atoms share electrons to form a bond. When the shared electrons are in p orbitals, they can overlap in a way that is perpendicular to the axis connecting the two bonded atoms. This overlap is called a pi bond, and it is stronger and shorter than a sigma bond, which forms from the head-to-head overlap of atomic orbitals. Pi bonds are found in double and triple covalent bonds, as well as in aromatic compounds.
