C
NO2- (nitrite
ion) is bent shaped (angular), O-N-O
bond angle ~120o due to two groups of bonding electrons
and one lone pair of electrons.
NO3- (nitrate ion)
is trigonal planar, O-N-O bond angle 120o due to
three bonding groups of electrons and no lone pairs of
electrons.
Add Answer to:
Are the O-N-O bond angles greater in the nitrite ion (NC2-) or the nitrate ion (NO3-)?...

Which of the following concerning electron pair space requirements and bond angles is/are incorrect? 1. Lone pairs of electrons require more space than bonding pairs. 2. Multiple bonds require the same amount of space as single bonds. 3. The HOH bond angle in H2O and the HNH bond angle in NH3 are identical because the electron arrangements (tetrahedral) are identical. Select one: a. 1 only b. 2 only c. 3 only d. 2 and 3 e. 1, 2, and 3

Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? The electron-pair geometry for NH3 is tetrahedral. with ______ bonding pair(s) of electrons and ______ lone pair(s) of electrons. A lone pair takes up more room than a single bond, causing the H–N–H angle to be smaller than the bond angle in a regular tetrahedron such as CH4. Why is the H–N–H angle in NH4+ identical to the H–C–H bond angle in CH4? The electron-pair...
