What is its shape? tetrahedral angular linear

Try again!! Go back

Angular…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Polar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

Dipole-Dipole…Very good! This molecule is angular because it has 4 e- pairs around the central atom, 2 atoms bonded to it, and 2 lone pairs. It is polar because it is angular with two lone pairs. Since it is polar, it will have a dipole-dipole IMF Back to Lewis Structures

What is its shape? Trigonal planar Pyramidal Tetrahedral

Trigonal Planar…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is trigonal planar because it has 3 e- pairs around the central atom, 3 atoms bonded to it, and 0 lone pairs. It is nonpolar and therefore will experience london dispersion intermolecular forces. Back to Lewis Structures

What is its shape? tetrahedral octahedral pyramidal

Try again!! Go back

Octahedral…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is octahedral because it has 6 e- pairs around the central atom, 6 atoms bonded to it, and 0 lone pairs. It is nonpolar so it will experience london dispersion intermolecular forces. Back to Lewis Structures

What is its shape? tetrahedral angular square planar

Try again!! Go back

Tetrahedral…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is angular because it has 4 e- pairs around the central atom, 4 atoms bonded to it, and 0 lone pairs. Since it is nonpolar it will experience london dispersion intermolecular forces. Back to Lewis Structures

What is its shape? tetrahedral pyramidal see saw

Try again!! Go back

See Saw…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Polar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

Dipole-Dipole…Very good! This molecule is see saw shape because it has 5 e- pairs around the central atom, 4 atoms bonded to it, and 1 lone pairs. It is polar because it has one lone pair which will distort the shape. Since it is polar, it will have a dipole IMF Back to Lewis Structures

What is its shape? tetrahedral trigonal planar pyramidal

Try again!! Go back

Trigonal planar…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is trigonal planar because it has 4 e- pairs around the central atom, 3 atoms bonded to it, and 0 lone pairs. It is polar because it is angular with two lone pairs. Since it is polar, it will have a dipole-dipole IMF **It is also ok to determine shape by saying 3 electron regions, 3 atoms bonded to it, and 0 lone pairs. You get the same answer Back to Lewis Structures

What is its shape? Square planar Pyramidal Octahedral

Try again!! Go back

Square Planar…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is square planar because it has 6 e- pairs around the central atom, 4 atoms bonded to it, and 2 lone pairs. Although it has lone pairs, it is nonpolar because it is one of the exceptions. The fluorines cancel each other out, as do the lone pair in this specific shape. Since it is nonpolar it experiences london dispersion intermolecular forces. Back to Lewis Structures

What is its shape? see saw angular linear

Try again!! Go back

Linear…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Nonpolar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

London Dispersion…Very good! This molecule is linear because it has 5 e- pairs around the central atom, 2 atoms bonded to it, and 3 lone pairs. Although it has lone pairs, this is one of the exceptions and is nonpolar since the lone pairs are on the same plane and cancel each other out. Since is it nonpolar, it will experience london dispersion intermolecular forces. Back to Lewis Structures

What is its shape? angular trigonal planar linear

Try again!! Go back

Angular…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Polar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

Dipole-Dipole…Very good! This molecule is angular because it has 4 e- pairs around the central atom, 2 atoms bonded to it, and 1 lone pair. It is polar because it is angular with a lone pair. Since it is polar, it will have a dipole-dipole IMF Back to Lewis Structures

Remember for any acid with an oxygen (starts with H and has an O), the hydrogen is bonded to one of the oxygen atoms What is its shape? tetrahedral angular trigonal planar

Try again!! Go back

Trigonal planar…Very good! What is the polarity? Polar Nonpolar

Try again!! Go back

Polar…Very good! What is its principal IMF? London Dispersion Dipole Hydrogen Bonding

Try again!! Go back

Hydrogen bonding…Very good! This molecule is trigonal planar because it has 4 e- pairs around the central atom, 3 atoms bonded to it, and 0 lone pairs. It is polar because all of the electrons around the central atom are not pulled equally because of the -OH group. Since it is polar and there is an oxygen atom covalently bonded to a hydrogen atom, this molecule will experience hydrogen bonding **It is also ok to determine shape by saying 3 electron regions, 3 atoms bonded to it, and 0 lone pairs.
