Q
Q: What is the bond angle in a water (H2O) molecule?
Solution:
The bond angle in water is approximately 104.5 degrees due to the repulsion of the two lone pairs.
Steps: 6
Show Steps
Step 1: Understand that a water molecule (H2O) has two hydrogen atoms and one oxygen atom.
Step 2: Know that the oxygen atom has two lone pairs of electrons that are not involved in bonding.
Step 3: Recognize that the two hydrogen atoms are bonded to the oxygen atom, forming a V-shape.
Step 4: Remember that lone pairs of electrons repel each other and the bonded pairs, affecting the shape of the molecule.
Step 5: Learn that the bond angle is the angle between the two hydrogen atoms in the water molecule.
Step 6: Conclude that the bond angle in water is approximately 104.5 degrees due to the repulsion from the lone pairs.
