We’re being asked to determine the shape of BCl3. The possible molecular shapes are:
To do so, we first need to draw a Lewis structure for BCl3. For this, we need to do the following steps:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Determine the shape of the molecule.
Determine the electron geometry (eg) and the molecular geometry of BCl3
a) eg = tetrahedral, mg = trigonal pyramidal
b) eg = trigonal planar, mg = bent
c) eg = trigonal planar, mg = trigonal planar
d) eg = trigonal bipyramidal, mg = trigonal bipyramidal
e) eg = tetrahedral, mg = triognal planar
