A stoneâs throw from Harvardâs ivied walls, surrounded by the bustling eateries, shops, and confectioners on Brattle Street (once called the Kingâs Road), Toscanoâs second location brings the bright, fresh flavors of Tuscany to historic Cambridge. Address. 52 Brattle Street, Cambridge, MA.
Share. By Anne Marie Helmenstine, Ph.D. Definition: A pi bond is a covalent bond formed between two neighboring atom's unbonded p-orbitals. An unbound p-orbital electron in one atom forms an electron pair with a neighboring atom's unbound, parallel p-orbital electron.This electron pair forms the pi bond.hare.

Benzene is the simplest aromatic compound with C6H6 molecular formula and contains three pi bonds arranged in alternate manner in hexagonal ring. The carbon-carbon bond length in benzene is intermediate to C-C single bond (154 pm) and C = C double bond (134 pm) that is 139 pm due to resonance in molecule.ince six pi electrons are delocalized over whole ring, therefore the cyclically conjugated double bonds represents by a circle and the carbon-carbon bond length becomes equal. This structure of benzene is called as resonance hybrid of benzene and generally used to represents the benzenemolecule.
