Question 2: Organic oxidation

Answer:

organic acids are oxidized to make alcohols

Question 3: alco-diol

Answer:

alcohol with 2 hydroxyl (OH) groups

Question 4: Functional groups

Answer:

on table R, changes that can be made or added to a hydrocarbon that make it into a whole different category of organic compound (ie. Ketone, ester)

Question 5: Alkane

Answer:

Hydrocarbon general formula CnH2n+2

Question 6: cracking or hydrolysis

Answer:

splitting large polymer hydrocarbons back down into their subunits by adding water

Question 7: Polymer

Answer:

a very long organic compound; comprised of repeated subunits

Question 8: Isomers

Answer:

have the same molecular formula but different structures

Question 9: Polymer

Answer:

several hydrocarbons linked together by addition polymerization or dehydration synthesis

Question 10: homologous series

Answer:

a family of hydrocarbons, like alkanes, they all contain the same general formula.

Question 11: triene

Answer:

contains 3 double bonds

Question 12: Fermentation

Answer:

start with a sugar and ends with ethanol and carbon dioxide

Question 13: Polymerization

Answer:

linking together small hyrdocarbons into longer chain by either removing water (condenstaion, dehydration) or breaking double bonds to single bonds (addition)

Question 14: Addition

Answer:

start with alkene or alkyne. Break apart the multiple bond and add 2 halogens. (one product only)

Question 15: Hydrogenation

Answer:

an addition reaction that uses hydrogen instead of a halogen

Question 16: examples of natural polymers

Answer:

silk, starch, cellulose

Question 17: hydrocarbon

Answer:

contains only hydrogen and carbon

Question 18: diene

Answer:

contains 2 double bonds

Question 19: Alkene

Answer:

Hydrocarbon with at least one double bond and general formula CnH2n

Question 20: Alcohol

Answer:

Organic compound that contains an -OH functional group

Question 21: Halide (Halocarbon)

Answer:

Organic compound that contains F, Cl, Br or I functional group

Question 22: Saponification

Answer:

NaOH +fatty acid yields soap and water

Question 23: organic chemistry

Answer:

study of carbon and its compounds

Question 24: Substitution

Answer:

start with an alkane, switch one hydrogen with a halogen. The other product is an acid

Question 25: Combustion

Answer:

HC fuel + Oxygen yields CO2 and water

Question 26: When is an organic cmpd "saturated?"

Answer:

contains ONLY single bonds

Question 27: Alkyne

Answer:

Hydrocarbon with at least one triple bond and general formula CnH2n-2
