Question

quiz #2
vsepr predicts an sbf5 molecule will be which of the following shapes?
○ tetrahedral
○ trigonal bipyramidal
○ square pyramid
○ trigonal planar
○ square planar
question 9 (1 point)
the molecules in the following set do not include which of the following shapes?
xef2, bf3, brf3, clo4-
○ t - shaped
○ trigonal planar
○ trigonal pyramidal
○ linear
○ tetrahedral

Explanation:

For the first question, in $SbF_5$, the central - atom $Sb$ has 5 bonding pairs and 0 lone pairs. According to VSEPR theory, it has a trigonal bipyramidal geometry. For the second question, $XeF_2$ is linear, $BF_3$ is trigonal planar, $BrF_3$ is T - shaped, and $ClO_4^-$ is tetrahedral. So the set does not include trigonal pyramidal shape.

Answer:

First question: B. trigonal bipyramidal
Second question: C. trigonal pyramidal
