determine the electron geometry (eg) and molecular geometry (mg) of bcl3.
eg=trigonal planar, mg=bent
eg=trigonal planar, mg=trigonal planar
eg=tetrahedral, mg=trigonal pyramidal
eg=trigonal bipyramidal, mg= trigonal bipyramidal
eg=tetrahedral, mg=trigonal planar

Explanation:

For $HCCl_3$, the central - carbon atom has 4 bonding pairs and no lone pairs. According to VSEPR theory, the molecular geometry is tetrahedral. For $BCl_3$, the central boron atom has 3 bonding pairs and no lone pairs. The electron - geometry and molecular geometry are both trigonal planar as per VSEPR theory.

Answer:

First question: C. tetrahedral
Second question: B. eg=trigonal planar, mg=trigonal planar
