Problem 53 - Chemistry: The Central Science

Question

Shown here are three pairs of hybrid orbitals, with each set at a characteristic angle. For each pair, determine the type of hybridization, if any, that could lead to hybrid orbitals at the specified angle.

Step-by-Step Solution

Answer

To determine the type of hybridization for each given pair of hybrid orbitals, compare their characteristic angles with the known bond angles for various hybridization types: 180° for sp, 120° for sp2, and 109.5° for sp3. For each pair, select the hybridization type whose bond angle matches closely to the given angle.

Step 1: Identifying Hybridization Types using Bond Angles

Recall that the bond angles for various types of hybridization are as follows: - For sp hybridization, the bond angle is 180°. - For sp2 hybridization, the bond angle is 120°. - For sp3 hybridization, the bond angle is 109.5°. Now, we can proceed to analyze each given pair of hybrid orbitals, and identify the hybridization type based on their characteristic angle.

Step 2: Pair 1

Determine the type of hybridization for the given pair of hybrid orbitals with their characteristic angle. Compare the angle with the known bond angles for various hybridization types and select the one that matches closely.

Step 3: Pair 2

Determine the type of hybridization for the given pair of hybrid orbitals with their characteristic angle. Compare the angle with the known bond angles for various hybridization types and select the one that matches closely.

Step 4: Pair 3

Determine the type of hybridization for the given pair of hybrid orbitals with their characteristic angle. Compare the angle with the known bond angles for various hybridization types and select the one that matches closely. Remember to consult the known bond angles for sp, sp2, and sp3 hybridization (180°, 120°, and 109.5° respectively) while comparing and selecting the correct hybridization type for each given pair of hybrid orbitals.
