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

a. nitrate ion

e. sulfur dioxide

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,

Therefore,

From the given options, the correct answer is -

a. nitrate ion

e. sulfur dioxide

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

i think   the answer is c hope i'm right
