|
True or False: Configuration of electrons determinds the kinds and number of bonds an atom will form with other atoms.
|
True. Electron configuration is the key to an atom's chemical characteristics
|
|
|
True or False: Carbon usually shares it's electrons to fill its valence shell
|
True. They include single and double covalent bonds.
|
|
|
What is tetravalence?
|
the ability for an atom (such as carbon) to branch off in 4 directions
|
|
|
True or False: When two carbon atoms are joined by a double bond, they form a tetrahedral.
|
False. They're on the same plane. When Carbon bonds to four other atoms, they take on a tetrahedral shape.
|
|
|
Why is carbon covalent compatible with many different elements?
|
Because of the electron configuration of Carbon
|
|
|
True or False: Carbon atoms are unable to form covalent bonds with other carbon atoms.
|
False. Carbon bonds are able to form covalent bonds with other carbon atoms making a chain of infinite variety.
|
|
|
True or False: Carbon skeletons vary in lenth.
|
True.
|
|
|
True or False: Carbon skeletons are only unbranched.
|
False. Carbon atoms may be branched or unbranched.
|
|
|
True or False: The skeleton of a carbon atom may have double bonds, but only in one location.
|
False. The double bonds may appear at any location
|
|
|
True or False: Carbon skeletons are unable to form rings.
|
False. Carbon skeletons are able to arrange rings.
|
|
|
What are hydrocarbons?
|
Molecules consisting of only carbon and hydrogen
|
|
|
True or False: Hydrocarbons are able to undergo reactions that release a relatively large amount of energy.
|
True. Ex: gas that fuels a car consists of hydrocarbons.
|
|
|
True or False: Hydrocarbons are prevalent in living organisms.
|
False. Though they are located in cells, they are not prevalent.
|
|
|
True or False: Compounds with the same number of atoms and same elements but different structure still have the same properties.
|
False. The structure tells their function, thus separate properties.
|
|
|
What are isomers?
|
compounds that have the same numbers of atoms of the same elements but different structures and hence different properties
|
|
|
Which isomer differs in the covalent arrangement of their atoms?
|
Structural isomers
|
|
|
Which isomer has the same covalent partnerships, but differ in spatial arrangements?
|
Geometric isomers
|
|
|
What causes geometric isomers to occur?
|
double bonds and their inflexibility
|
|
|
Consider a simple molecule with 2 double-bonded carbons, each of which has an H and an X attached to it. What is the name of the isomer with both Xs on the same side of the double bond?
|
cis isomer
|
|
|
Consider a simple molecule with 2 double-bonded carbons, each of which has an H and an X attached to it. What is the name of the isoer with Xs on opposite sides of the double bond?
|
trans isomer
|
|
|
Which isomers are mirror images of each other?
|
Enantiomers
|
|
|
What is the name of a carbon with four attached groups?
|
asymmetric carbon
|
|
|
How are gasoline and fat similar?
|
both consist of largely of hydrocarbon chains
|
|
|
Can propane (C3H8) form isomers?
|
No. Not enough diversity
|
