Shapes of Molecules
Question | Answer |
---|---|
What determines the shapes of the molecules? | The number of electron pair there is surrounding the central atom |
What is the shape called with a 180 angle? | Linear |
What is the bond angle in a Trigonal Planar Shape? | 120 |
What is the bond angles in a Tetrahedral shape? | 109.5 |
What is the shape called with a 107 bond angle? | Pyramidal |
What is the bond angle in a Trigonal Bipyramidal Shape? | 120 + 90 |
What is the bond angle in a Non-linear shape? | 104.5 |
How many lone pairs of electrons are in a Pyramidal Shape? | 1 |
How many lone pairs of electrons are in a Non Linear shape? | 2 |
By how much does a lone pair of electrons reduce the bond angle by? | 2.5 |
Why do lone pairs reduce the bond angle? | Because there is an extra repulsive effect from each lone pair |
