Carbon chemistry 1 Flashcards
What is organic chemistry referring to?
the chemistry of carbon
What is the atomic weight of carbon?
12
What is carbon the basis of?
all known living organisms
fuel combustion
How many known compounds containing hydrogen and carbon are known of by chemists?
7 million
What type of bond forms between carbon atoms?
strong covalent bonds
What forms can the covalent bonds between carbons be found in?
single
double
triple
What ways can carbon atoms be arranged?
Straight chains
Branched chains
Rings
What are functional groups? (carbon atoms)
Other atoms/groups of atoms can be
placed on the carbon atoms
Why can functional groups be placed onto carbon atoms?
as they can be placed in different positions on the carbon skeleton
What are the 2 main classes of carbon compound?
Aliphatic
Aromatic
Where did the aromatic carbon class get its name?
The original chemists noticed a sweet aroma which lined up with those carbon compounds with double bonds
What are aliphatic carbon compounds?
only contain single bonded carbons
How can aliphatic carbons be sub-divided?
Acyclic - no ring formed
Alicyclic - form rings
What are the simplest molecules that are composed of just C and H?
Alkanes
Alkenes
Alkynes
What is a Homologous series?
a family of compounds whose formulae differ by a constant component
What are the 4 smallest base families of carbon hydrogen?
Methane - CH4
Ethane- C2H6
Propane (camping gas)- C3H8
Butane- C4H10
What are the carbon hydrogen names with the number of carbon atoms?
Pentane- 5
Hexane- 6
Heptane- 7
Octane- 8
Nonane- 9
Decane- 10
Undecane- 11
Dodecane- 12
What are isomers?
compounds that have the same molecular
formula, but different molecular structures
What happens to the number of isomers as the length of carbon chain increases?
more structural isomers are possible
How many isomers can decane have?
75
