What is geometry of Ammonia?
1)trigonal planar
2)square planar
3)T-squared
4)trigonal pyramidal
5)tetrahedral
What is the bond angle of Ammonia?
1)109.5
2)less than 90
3)less than 109.5
4)90
5)120
Are thought the answer to the second question was 3 not 2 because does ammonia have a 107 degree angle?
4 for molecular geometry; 5 for electronic geometry.
To determine the geometry of ammonia (NH3), we need to consider its electron and molecular geometry.
Step 1: Determine the electron geometry:
- Ammonia has 4 regions of electron density around its central atom (3 bonding pairs and 1 lone pair).
- The electron geometry is determined by the arrangement of these regions, which in this case is called "tetrahedral".
Step 2: Determine the molecular geometry:
- The molecular geometry only considers the arrangement of the bonded atoms, ignoring the lone pairs.
- Since ammonia has one lone pair, the molecular geometry will be different from the electron geometry.
- The lone pair exerts more repulsion than the bonding pairs, causing the bonded atoms to be pushed closer together.
- Therefore, the molecular geometry of ammonia is "trigonal pyramidal".
So, the correct answers are:
- Geometry of Ammonia: 4) trigonal pyramidal
- Bond angle of Ammonia: 3) less than 109.5 degrees
