Question

question 10 (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 (Regions of Electron Density): Count all electron - density regions (bonding + non - bonding). In the given structure, there are 5 regions.
• Bonding REDs: Count the number of atoms bonded to the central atom. Here, there are 3 bonding regions.
• Non - bonding REDs: Subtract the number of bonding regions from the total REDs. \(5 - 3=2\) non - bonding regions.
• Shape: For a molecule with 5 REDs (3 bonding and 2 non - bonding), the shape is T - shape.
• Bond Angles: In a T - shaped molecule, the bond angles are \(90^{\circ}\) and \(180^{\circ}\).

Answer:

1. F. 5
2. D. 3
3. C. 2
4. P. T - shape
5. Y. \(90^{\circ}\) and \(180^{\circ}\)
