Question

question 5 (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 the total electron - density regions (bonding + non - bonding). In this case, there are 4 (4 single bonds or bonding pairs).
• Bonding REDs: All 4 are bonding (no lone pairs shown as non - bonding regions in the structure).
• Non - bonding REDs: 0 (no lone pairs).
• Shape: For 4 bonding regions and 0 non - bonding regions, the shape is tetrahedral.
• Bond angles: In a tetrahedral geometry, the bond angles are \(109.5^{\circ}\).

Answer:

1. E. 4
2. E. 4
3. A. 0
4. L. tetrahedral
5. U. \(109.5^{\circ}\)
