Question

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:

Step1: Count REDs (Regions of Electron Density)

From the structure, we can see that there are 6 regions of electron density (3 non - bonding pairs and 3 bonding pairs).

Step2: Count Bonding REDs

There are 3 bonding regions (the green atoms attached to the central red atom).

Step3: Count Non - bonding REDs

There are 3 non - bonding regions (the blue electron - pair clouds).

Step4: Determine Molecular Shape

The shape with 6 REDs (3 bonding and 3 non - bonding) is octahedral.

Step5: Determine Bond Angles

In an octahedral shape, the bond angles are \(90^{\circ}\) and \(180^{\circ}\).

Answer:

1. G. 6
2. D. 3
3. D. 3
4. Q. octahedral
5. Y. \(90^{\circ}\) and \(180^{\circ}\)
