Question

Are the O-N-O bond angles greater in the nitrite ion (NO2-) or the nitrate ion (NO3-)? Please select the answer that best explains your conclusion.

a. Nitrite has the greater bond angle because a trigonal planar bond angle is greater than a tetrahedral bond angle.

b. Nitrite has the greater bond angle because a linear bond angle is greater than a trigonal planar bond angle.

c. Nitrate has the greater bond angle because nitrite's lone pairs take up more space than bonds.

d. Nitrate has the greater bond angle because double bonds take up more space than single bonds.

Explanation / Answer

answer : c. Nitrate has the greater bond angle because nitrite's lone pairs take up more space than bonds.

explanation:

Nitrate ion shape is planar shape bond angle is about to 120 degree.

but in NO2- bond angle is lesser than than the NO3- it is due to one lone pair present on NO2- . its shape is bent shape and bond angle is deviated from 120 degrees
