Question

question 6 (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): The central atom has 4 regions of electron density (3 bonding pairs and 1 non - bonding pair).
• Bonding and Non - bonding: There are 3 bonding regions (to the green atoms) and 1 non - bonding region (the lone pair on the blue atom).
• Shape: With 3 bonding and 1 non - bonding region, the molecular shape is pyramidal (based on VSEPR theory).
• Bond Angles: For a pyramidal shape (derived from a tetrahedral electron - pair geometry with one lone pair), the bond angles are approximately \(109.5^{\circ}\) (slightly less due to the lone - pair repulsion, but the closest standard value is \(109.5^{\circ}\)).

Answer:

1. E. 4
2. D. 3
3. B. 1
4. M. pyramidal
5. U. \(109.5^{\circ}\)
