Checked by teacher
True or False: PF5 has a trigonal pyramidal electron geometry
False, its trigonal BIpyramidal
How many bonded atoms does CH4 have?
4
What is the bond angle that is assigned to tetrahedral category and shape?
109.5
What is the electron geometry of CO2?
Linear
True or False: PCl3 has 2 lone pairs
False
How many electron domains will a molecule with octahedral electron geometry have?
6
Which has more bonded atoms? HCN or CO2
Neither, they have the same amount
What happens to the bond angle when you have a lone pair on the central?
It makes the angle smaller
What is the difference between electron geometry and molecular geometry?
Electron Geometry - Category, Molecular Geometry - Shape
How many bonds connect the C and N in HCN?
3
Which has more lone pairs? Trigonal pyramidal shape or Bent shape in the tetrahedral category?
True or False: carbon tetrachloride has 3 bonded atoms and 1 lone pair
False
True or False: The bond angle for PCl3 is 109.5
False, it is LESS THAN 109.5
Which molecular has tetrahedral electron and molecular geometry? CH4 or NH3?
CH4
Which molecule has more lone pairs? NH3 or CH3Cl
NH3
What electron and molecular geometry has 4 bonded atoms and 1 lone pair?
Trigonal Bipyramidal, seesaw
True or False: The more bonded atoms you add, the smaller the bond angle gets
True
Where do lone pairs go after you've subtracted 2 for each bond from the total?
They start getting put on the outside atoms first
What is VSEPR Theory?
Determining the shape of a molecule
CH2O has what electron geometry?
Trigonal Planar
What is the electron and molecular geometry of PCl5
Trigonal Bipyramidal x 2
When drawing the lewis dot structure, how many do you subtract from the total for each bonded atom you add?
2 for each bonded atom
Why does adding lone pairs make the bond angle less?
The lone pair takes up a little more space than bonded atoms
What makes a bong angle become less than the usual angle?
A lone pair on the central atom
