What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

Front

Define tetrahedral molecular geometry.

Back

Tetrahedral molecular geometry occurs when a central atom is bonded to four other atoms, forming a shape with bond angles of approximately 109.5 degrees.

Front

What is the bond angle in a tetrahedral molecule?

Back

The bond angle in a tetrahedral molecule is approximately 109.5 degrees.

Front

What is trigonal pyramidal molecular geometry?

Back

Trigonal pyramidal molecular geometry occurs when a central atom is bonded to three other atoms and has one lone pair, resulting in a pyramid-like shape.

Front

Define bent molecular geometry.

Back

Bent molecular geometry occurs when a central atom is bonded to two other atoms and has one or more lone pairs, resulting in a non-linear shape.

Front

What is octahedral molecular geometry?

Back

Octahedral molecular geometry occurs when a central atom is bonded to six other atoms, forming an octahedron with bond angles of 90 degrees.

Front

What is trigonal bipyramidal molecular geometry?

Back

Trigonal bipyramidal molecular geometry occurs when a central atom is bonded to five other atoms, resulting in two different bond angles: 90 degrees and 120 degrees.

Front

Identify the molecular geometry of water (H2O).

Back

Water (H2O) has a bent molecular geometry due to the two lone pairs on the oxygen atom.

Front

What is the molecular geometry of ammonia (NH3)?

Back

Ammonia (NH3) has a trigonal pyramidal molecular geometry due to one lone pair on the nitrogen atom.

Front

Define square planar molecular geometry.

Back

Square planar molecular geometry occurs when a central atom is bonded to four other atoms in a plane, with 90-degree bond angles, typically seen in compounds with two lone pairs.
