What is the electron-domain geometry and molecular geometry of ammonia?
A.Tetrahedral; trigonal pyramidal
B.Tetrahedral; tetrahedral
C.Trigonal planar; trigonal pyramidal
D.Trigonal planar; trigonal planar
Explanation
Core Concept
Four domains (three bonds + one lone pair) give tetrahedral electron geometry. The three atoms then describe a trigonal pyramid, with the lone pair occupying the fourth corner.
Correct Answer
ATetrahedral; trigonal pyramidal
