Chemical Bonding & Isomers Pages
Recall the petroleum refining…. What is this next slide a diagram of?
What are intermolecular forces?
The larger the hydrocarbon molecules, the _______________, the intermolecular force. The larger the hydrocarbon molecules, the STRONGER the intermolecular force.
The larger the hydrocarbon molecules, the _______________, the boiling point. The larger the hydrocarbon molecules, the HIGHER the boiling point.
Do you remember why atoms are attracted to other atoms? How many valence electrons does a C atom have?
Ions and Ionic bonding From pages
Find Mg on the Periodic Table…
If an atom of Mg became an ion, How does its electron structure change? What would be its charge? What would it be classified as?
If an atom of F became an ion, How its electron structure change? What would be its charge? What would it be classified as?
Chemical Bonding Organic chemistry – study of hydrocarbons and their derivatives Hydrocarbons – composed of carbon chains (backbone) with H atoms attached to remaining bonding sites
Chemical Bonding Electron-dot formulas Each dot represents 1 valence e - Dots placed between chem symbols represent electrons shared by atoms
Single covalent bond – a pair of electrons are shared between two atoms Ex) methane CH 4 Carbon has 4 valence e - 4 H each have 1 valence e -
Structural formulas A line can be used to represent a pair of shared e - Remember – molecules are not 2-dimensional
Alkanes Alkanes - Simple hydrocarbon family Each C forms single covalent bonds w/ 4 other atoms Because each C atom is bonded to the maximum # of other atoms, it is said to be saturated
Alkanes Straight-chain alkane – each C is linked to only 1 or 2 other C atoms
Alkanes Branched-chain alkane – 1 or more C are linked to 3 or 4 other C atoms
Isomers - molecules with identical chemical formulas but different structural formulas Ex) octane C 8 H 18
Isomers and Boiling Point Q. Which isomer would have the lowest boiling point temperature?
Isomers and Boiling Point A.The molecule on the right… branched shaped decreases surface area which results in weaker intermolecular forces. This makes it easier for the molecules to evaporate.
Ch 19 Test Review. Stability in Bonding Vocabulary Chemical Formula Be able to write the chemical formula of a given compound Chemically Stable Which.
Warmup: Think back to the structure of the atom and draw a Carbon atom. How many valence electrons does carbon have?
Chemical Bonds Chapter Ionic Bonding 6.2 Covalent Bonding.
Ch. 12 Chemical Bonding 12.1 Ionic, covalent and polar covalent bonds. A bond is a force that holds atoms together. Ionic Bonding a. When a metal reacts.
Chapter 8 – Compounds of Carbon. Why is Carbon Important? Carbon compounds make up over 90% of all chemical compounds. They also form the basis of living.
Why do some solids dissolve in water but others do not? Why are some substances gases at room temperature, but others are liquid or solid? What gives.
Chapter 6 Covalent bonding. Makes molecules Specific atoms joined by sharing electrons Molecular compound Sharing by different elements Diatomic molecules.
Chapter 4 The Structure of Matter How atoms form compounds.
CI 13.2 – Alcohols and Ethers (C) JHUDSON Draw two different structures with the molecular formula C 2 H 6 O Remember carbon bonds to 4 other atoms,
Chemical Bonding. Why the noble gaes are so noble… The elements in group 18 are known as the noble gases. They are completely unreactive The other elements.
Boiling Points Andrew, Annie, Paulina, Claudia. What Is Boiling Point? The temperature at which the vapor pressure of the liquid equals the environmental.
BONDING AND STRUCTURES. Metallic (metals) TYPES OF BONDING.
CHAPTER 11 CONCURRENT ENROLLMENT. CARBON Organic compound Organic compound A compound that contains the element carbon A compound that contains the element.
Chemistry Daily 10’s Week A mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together.
