Question

what molecular shape is shown by this molecular model? trigonal bipyramidal octahedral trigonal pyramidal tetrahedral

Explanation:

To determine the molecular shape, we analyze the model:

• A trigonal bipyramidal shape has 5 bonding groups, with bond angles of 90° (between axial and equatorial) and 120° (between equatorial groups). The model shows 5 orange atoms (bonding groups) around the central atom, with angles 90° and 120°, matching trigonal bipyramidal.
• Octahedral has 6 bonding groups (all 90° angles), trigonal pyramidal has 3 bonding + 1 lone pair (pyramidal shape), and tetrahedral has 4 bonding groups (109.5° angles). These don’t match the model.

Answer:

A. trigonal bipyramidal
