Question

question 9 (0.5 points)
the following shape has 1 reds, 2 are bonding and 3 are nonbonding.
the shape is called 4 and the bond angles are 5.
a. 0 b. 1 c. 2 d. 3 e. 4 f. 5 g. 6 h. diatomic
i. linear j. planar trigonal k. bent l. tetrahedral m. pyramidal
n. hexahedral o. seesaw p. t - shape q. octahedral r. square
pyramidal
s. square planar t. 90° u. 109.5° v. 120° w. 180°
x. 90°, 120°, and 180° y. 90° and 180°

Explanation:

• REDs (Region of Electron Density): Count the total number of electron - density regions (bonding and non - bonding). In this structure, there are 5 regions (4 bonding and 1 non - bonding).
• Bonding and Non - bonding REDs: By observing the structure, we can see that 4 are bonding (connected to atoms) and 1 is non - bonding (lone pair).
• Shape Name: Based on the VSEPR (Valence Shell Electron Pair Repulsion) theory, with 5 REDs (4 bonding and 1 non - bonding), the shape is seesaw.
• Bond Angles: For a seesaw - shaped molecule, the bond angles are \(90^{\circ}\), \(120^{\circ}\), and \(180^{\circ}\).

Answer:

1. F. 5
2. E. 4
3. B. 1
4. O. seesaw
5. X. \(90^{\circ}\), \(120^{\circ}\), and \(180^{\circ}\)
