Bond Angles And Shapes Flashcards
(8 cards)
1
Q
Linear bond angle and reason
A
180 - 2 bonded pairs
2
Q
Trigonal planar bond angle
A
120 - 3 bonded pairs
3
Q
Non-linear (Bent) bond angle
A
104.5 - 2 bonded pairs of electrons - 2 lone pairs ( each lone pair reduces the angle by 2.5 degrees)
4
Q
Pyramidal bond angle
A
107 -3 bonded pairs and 1 lone pair
5
Q
Tetrahedral bond angle
A
109.5 - 4 bonded pairs of electron 0 lone pairs
6
Q
Octahedral bond angle
A
90 - 6 bonded pairs
7
Q
What shape and bond angle would Boron trifluoride have?
A
120 - there are only 3 bp
8
Q
What would the bond angle between H-O-N be in HNO3?
A
104.5- 2 bp and 2lp - lp repel more
