Answer:
A) and D)
Explanation:
A) BF 3 has a trigonal planar shape
TRUE.
BF₃ has three bonding pairs and no lone pairs. According to VSEPR theory, it is an AX₃ molecule with trigonal planar geometry.
B) Molecules with three outer atoms always have a trigonal planar shape.
False
NH₃ has three outer atoms but a trigonal pyramidal shape.
C) NH₃ has a trigonal planar shape
False.
NH₃ has three bonding pairs and one lone pair. According to VSEPR theory, it is an AX₃E molecule with trigonal bipyramidal geometry.
D) Trigonal planar molecules have three regions of high-electron density around the central atom
TRUE
The regions of high-electron density are the three bonding pairs.
