Question

Among the following, molecules, which one have trigonal planar structure ?
`XeO_(3), SO_(3), BF_(3), NH_(3)`
A. `XeO_(3) and BF_(3)`
B. `BF_(2) and SO_(3)`
C. `NH_(3) and SO_(3)`
D. All of the above

Answer 1

Correct Answer - B
In `BF_(3), H=(3+3)/(2)=3 (sp^(2))`
In `SO_(3), H=(6+0)/(2)=3 (sp^(2))`
