The correct Answer is:
To determine the correct order of bond angles for the species NO2+, NO2, and NO2-, we will analyze the bond angles based on their molecular geometries and the effects of lone pairs of electrons. ### Step 1: Identify the molecular geometries - **NO2+ (Nitronium ion)**: This species has a linear geometry due to the absence of lone pairs on the nitrogen atom. The bond angle is 180 degrees. - **NO2 (Nitrogen dioxide)**: This molecule has a bent geometry due to one lone pair of electrons on the nitrogen atom. The bond angle is approximately 134 degrees. - **NO2- (Nitrite ion)**: This species also has a bent geometry, but it has two lone pairs of electrons on the nitrogen atom. The bond angle is reduced to about 115 degrees. ### Step 2: Compare the bond angles Now, we can summarize the bond angles: - NO2+ has a bond angle of 180 degrees. - NO2 has a bond angle of 134 degrees. - NO2- has a bond angle of 115 degrees. ### Step 3: Establish the order of bond angles From the values obtained: - NO2+ (180°) > NO2 (134°) > NO2- (115°) ### Conclusion The correct order for the bond angles is: **NO2+ > NO2 > NO2-**
