Bonding Review

Ionic, covalent, metallic

100

In this type of bond, electrons are transferred from a metal atom to a nonmetal atom

Ionic bond

200

In a covalent bond, electrons are ______________________ between two _________________________ atoms

shared, nonmetal

300

This is the type of bond in in which electrons are free to swarm around many positive nuclei and are not bound to any nucleus in particular

Metallic

400

If a substance is solid at room temperature, dissolved easily in water, and has a high melting point it is most likely this type of compound

Ionic

500

If a substance is solid at room temperature, is very ductile and malleable, and conducts electricity well, it is most likely this type of compound 

Metallic

Molecular geometry

100

H₂O has this shape

Bent

200

CO₂ has this shape

Linear

300

BH₃ has this shape

Trigonal planar

400

NH₃ has this shape

Trigonal pyramidal

500

SiF₄ has this shape

Tetrahedral

Polarity

100

Polarity is the uneven (or asymmetrical) sharing of these things within a molecule

electrons

200

If an atom has asymmetrical geometry and is made of atoms with very different electronegativity values it is.....

Polar

300

CO₂, CH₄, and O₂ are all examples of what type of molecules

nonpolar

400

If a substance dissolves in water, it is most likely....

Polar

500

Make a lewis dot diagram of a polar compound that has a trigonal pyramidal geometry

Examples: NH₃, PCl₃, NF₃

Intermolecular Forces

100

If a substance has extremely strong intermolecular forces, it will most likely be this state of matter at room temperature

Solid

200

If an ionic compound is dissolved in a polar solvent like water, which intermolecular force is strongest in the solution?

Ion-dipole

300

Which intermolecular force is strongest in a sample of the following compound: O₂

London dispersion

400

Which intermolecular force is strongest in a sample of the following compound: CH₃OH

Dipole-dipole (Hydrogen bonding)

500

Which intermolecular force is strongest in a solution of sugar (C₆H₁₂O₆) dissolved in water?

Hydrogen bonding (sugar is not ionic, so there are no ion-dipole forces)

Potpourri

100

What's my puppy's name?

Luna

200

The best things to get rid of spicy hot pepper taste in your mouth are milk, oils, and fats. Water doesn't work well.

What can we say about the polarity of the "spicy" chemical capsicum?

It is nonpolar (not water soluble)

300

This is the ability of a metallic compound to be easily bent and reshaped without breaking

Malleability

400

Which of these is a polar bond:

O--O, N--H, B--C

N--H

500

Which compound has the greatest London Dispersion Forces?

H₂O, CH₃OH, C₆H₁₂O₆

C₆H₁₂O₆ (It is the biggest/ heaviest)
