Question
What type of bonding around a central atom would result in a trigonal planar molecule?A.One group bound to it with two lone pairsB.Three groups bound to it with no lone pairsC.Four groups bound to it with no lone pairsD.Three groups bound to it with one lone pair
Solution
The type of bonding around a central atom that would result in a trigonal planar molecule is B. Three groups bound to it with no lone pairs.
Here's why:
A molecule is trigonal planar when it has three groups attached to the central atom and no lone pairs. This arrangement results in a molecule that is flat, or planar, and the bond angles are approximately 120 degrees.
Option A, one group bound to it with two lone pairs, would result in a bent or V-shaped molecule, not a trigonal planar one.
Option C, four groups bound to it with no lone pairs, would result in a tetrahedral molecule.
Option D, three groups bound to it with one lone pair, would result in a trigonal pyramidal molecule.
So, the correct answer is B. Three groups bound to it with no lone pairs.
