Question

question 3
the vsepr theory model only considers electron - pair
attractions
repulsions
collisions
annihilations

question 4
1 pts
the bef₂ molecule adopts a structure in which the two pairs of electrons, which comprise the two bonds, are as far apart as possible
bent
tetrahedral
linear
trigonal pyramidal
trigonal planar

Explanation:

For Question 3, VSEPR theory is based on minimizing electron - pair repulsions to predict molecular geometry. For Question 4, in BeF₂, the central beryllium atom has two bonding pairs and no lone pairs. According to VSEPR, two electron - pair groups arrange themselves to be 180° apart, resulting in a linear structure.

Answer:

Question 3: B. repulsions
Question 4: C. linear
