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

REDs (regions of electron density) include bonding and non - bonding pairs. There are 3 regions (2 bonding with green atoms and 1 non - bonding with blue atom).

Step2: Determine bonding and non - bonding REDs

From the structure, 2 are bonding (to green atoms) and 1 is non - bonding (blue atom).

Step3: Identify the shape

The shape with 3 REDs (2 bonding, 1 non - bonding) is pyramidal.

Step4: Find bond angles

For a pyramidal shape (based on tetrahedral electron - pair geometry with one non - bonding pair), the bond angles are approximately \(109.5^{\circ}\).

Answer:

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