Question

the structure shown here is of bcl₃. in this molecule, boron and chlo atoms are bonded through covalent bonds, where electrons are sh between the atoms. based on the arrangement of these atoms and electron pairs around the central boron atom, what is the molecular of bcl₃?

Explanation:

In \( BCl_3 \), boron (\( B \)) has 3 valence electrons and forms 3 covalent bonds with chlorine (\( Cl \)) atoms. There are no lone pairs on the central boron atom. According to VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when a central atom has 3 bonding pairs and no lone pairs, the molecular geometry is trigonal planar. The bond angles are \( 120^{\circ} \) and the three \( B - Cl \) bonds are in the same plane.

Answer:

trigonal planar
