The electron-domain geometry and molecular geometry of iodine trichloride are ________ and ________,respectively.
A)trigonal bipyramidal, trigonal planar
B)tetrahedral, trigonal pyramidal
C)trigonal bipyramidal, T-shaped
D)octahedral, trigonal planar
E)T-shaped, trigonal planar

Question

Quizplus · Accepted Answer

Iodine trichloride has five electron domain pairs, which gives it a trigonal bipyramidal electron-domain geometry. However, there are only three bonding pairs and two lone pairs, which gives it a T-shaped molecular geometry. Therefore, the correct answer is choice C, trigonal bipyramidal electron-domain geometry and T-shaped molecular geometry.
