Is ammonia molecule a tetrahedral?
The bond angles between two N-H bonds in ammonia are close to the bond angles characteristic of a tetrahedron, but the molecule as a whole is not a tetrahedron because one of the four bonds to a central atom found in an actual tetrahedral molecule is missing; there are only three hydrogen atoms bound to a central nitrogen atom in ammonia. In an ammonium ion, however, the tetrahedron is complete.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
The presence of lone pairs on the oxygen atom in a water molecule creates an uneven distribution of charge, with the oxygen being partially negative and the hydrogen atoms being partially positive. This charge separation makes the water molecule polar, as it has a positive and negative end.
What is the bond angle in pocl3?
The bond angle in POCl3 is approximately 107 degrees. This can be explained by the molecule's structure, which is trigonal pyramidal with one lone pair of electrons on the central phosphorus atom, causing some compression of the bond angles.
Predict the bond angle for the molecule h2s?
Polar bonds occur when the atoms that are bonded have an unequal sharing of electrons, they are not polar but just do not share electrons equally. Polar molecules occur when the molecule has polar bonds that are not equally distributed ie water is polar molecule because its polar bonds act at 104.5 degrees from one another whereas a molecule that was straight, 180 degrees, would not be polar due to the equal distribution of the bonds. A tetrahedral molecule has bonds going equally in four directions, therefore, no polar bond but ammonia which is trigonal pyramidal has three bonds acting downwards at 104 degrees from one another, therefore, it is a polar molecule.
How does a lone pair contribute to the molecular shape?
A lone pair of electrons can affect the molecular shape by repelling bonded pairs of electrons, causing distortions in the molecule's geometry. This can lead to changes in bond angles and overall molecular shape.

What configurations would form a bent molecule?
Any linear molecule in which the central atom has one or more lone pairs on it. Oxygen is the best example. The large negative charge on the lone pairs will force the electrons in the sigma bonds between the atoms away from itself, bending the structure.

What causes the difference in bond angles between carbon dioxide and water?
The difference in bond angles between carbon dioxide and water is caused by the arrangement of the atoms and the presence of lone pairs of electrons. In carbon dioxide, the molecule is linear with a bond angle of 180 degrees because there are no lone pairs on the central carbon atom. In water, the molecule is bent with a bond angle of about 104.5 degrees due to the presence of two lone pairs on the central oxygen atom, which repel the bonded pairs and compress the bond angle.
What are the bond angles in a molecule of CO2?
The bond angles in a molecule of CO2 are approximately 180 degrees.
What are the bond angles in a molecule of CHCl3?
The bond angles in a molecule of CHCl3 are approximately 109.5 degrees.
Which molecule has bond angles that are not reflective of hybridization?
The molecule that has bond angles not reflective of hybridization is ammonia (NH3).
What is the vsepr theory for an ammonia molecule?
The VSEPR theory for an ammonia (NH3) molecule predicts that the molecule has a trigonal pyramidal shape. This is because the nitrogen atom has one lone pair of electrons, causing the bond angles to be slightly less than the ideal 109.5 degrees.
What are the bond angles in a molecule containing SO2?
The bond angles in a molecule containing SO2 are approximately 120 degrees.
