2.2 Bonding and Structure Flashcards
1
Q
what does each lone pair do to the bond angle?
A
it will reduce the bond angle by 2.5 degrees - e.g. if there are 2 lone pairs in a molecule then you would do 109.5-(2.5 times 2)
2
Q
linear
A
180 degrees
3
Q
trigonal planar
A

4
Q
non-linear
A
104.5 degrees (109.5-(2.5 times 2))
5
Q
pyramidal
A
107 degrees (109.5-2.5)
6
Q
tetrahedral
A
109.5 degrees (need to just learn it)
7

90 degrees
8
Q
trigonal bipyramidal
A
120 degrees and 90 degrees
