Test #3- Unit #6

Intro to Bonding

100

Covalent compounds can be classified as being either polar or _______, which represent an equal share of electrons

What is non polar

200

These types of molecules do not exist by themselves in nature, they always come in pairs

What is a diatomic molecule

300

Ionic compounds structure is this, which allows for their pretty shapes and conductive properties

What is crystal lattice?

400

In this type of compound, electrons are shared amongst the atoms within the compound

What are covalent compounds

500

Using this acronym, you can remember what elements must always have a twin

What is BrINClHOF

VSEPR (P1)

100

This rule states that all atoms (except hydrogen) require 8 valence electrons

What is the octet rule

200

The first bond between two atoms is also known as this type of bond

What is the sigma bond

300

These are two unbonded electrons that hang around a single atom, they can be used to make atoms happy

What are lone pairs

400

If you have too many electrons in your structure, you can erase this many dots and draw one line between the central atom and one of the substituents (appendage atoms)

 What is four

500

Electron pairs, not to be confused with lone pairs, is the sum of these two things that help us determine the shape of a molecule using the VSEPR hand out

What are lone pairs + single bonds?

VSEPR (P2)

100

This type of bond can only be found in double and triple bonds. 

What are pi bonds

200

This molecule, SiO₃ ^2-, with three electron pairs (or three regions of electron density), has this shape

What is trigonal planar

300

Some molecules have negative charges, such as the polyatomic ions, to account for this, when finding the total number of valence electrons, we do this math operation with the charge number

What is add

400

This molecule, PO₃ ^3-, is commonly referred to as phosphite, and has this many total valence electrons

what is 26 ve^-

500

This molecule, H₂O, has a molecular shape of this, and a bond angle of this. 

What is bent and 120 degrees

IMFs

100

These types of forces do NOT form actual bonds between atoms, but use forces to hold molecules together. 

What are intermolecular forces?

200

This IMF, is the predominant IMF in all non polar molecules

What is London Dispersion Forces (LDFs)

300

Hydrogen bonds, the strongest of the IMFs, only happens in polar molecules where hydrogen is bonded to any of these three atoms

What are fluorine, oxygen, and nitrogen

400

This intermolecular force occurs when there is a permanent unequal share of electrons in the molecule

What is dipole-dipole

500

melting point and boiling points are determined by the strength of intermolecular forces, the order from weakest to smallest is this

What is LDFs, Dip-Dip, H-Bonds

Hybridization

100

When finding out how many orbitals to hybridize, you add up the total number of these two things

What is lone pairs and sigma bonds 

200

This molecule is acetaminophen, which is found in Tylenol, the hybridization of the nitrogen is this

What is sp₃

300

This molecule, ethanol, is commonly found in alcohol. What is the hybridization of the oxygen?

What is SP₃

400

This molecule, urea, is commonly found in urine. What is the hybridization of the carbon?

What is sp₂

500

This molecule, cyanoacrylate, is commonly found in super glue. What is the hybridization of the nitrogen?

What is sp
