Question

Which molecule or ion below would be expected to have a trigonal planar electron domain geometry?

a. nitrate ion, NO3 1-
b. at least two of these
c. carbon tetrachloride
d. water
e. sulfur dioxide

Answer 1

a. nitrate ion

e. sulfur dioxide

Step-by-step explanation:

Trigonal planar geometry, is possible, where the combination of atoms or lone pain form a triangle which is is same plane.

Hence, from the given options,

• Nitrate ion has a trigonal planar geometry.

• Carbon tetrachloride has a teterahedral geometry
• water has a bent angular geometry.
• sulfur dioxide has a trigonal planar geometry.

Therefore,

From the given options, the correct answer is -

a. nitrate ion

e. sulfur dioxide
