Answer 13

Alphabetical

Question 14

Start off with the ____ number

Answer 14

Lowest

Question 15

What is the least reactive hydrocarbon

Answer 15

Alkane- double and triple bonds are reactive because they want to become single bonds to become saturated

Question 16

When you have a ring, make sure you put ___

Answer 16

Cyclo

Question 17

Additional functional groups are chlorine, fluorine, bromine, and iodine are are denoted by_____…

Answer 17

Chloro, fluoro, bromo, iodo

Question 18

You assign double/triple bonds the lowest number possible, even if that means giving functional group higher numbers
True or false

Answer 18

True

Question 19

The direction of the numbering must go ___ the double/triple bond

Answer 19

Through

Question 20

Decribe the properties of a carbon atom that allow it to be the foundation of all organic compounds

Answer 20

4 valence electrons, it’s ability to form stable bonds

Question 21

What does it mean for a hydrocarbon to be saturated

Answer 21

They only have single bonds

Question 22

Why does water not mix with liquid hydrocarbons

Answer 22

Hydrocarbons are nonpolar and water is polar

These two will not mix together

Question 23

What. Is the relationship between the number of carbon atoms and the boiling points of the alkanes

Answer 23

As the number of carbons in the chain increases, the boiling points increase

Question 24

Why or cis or trans isomers not possible around a single or triple bond

Answer 24

Single bonds rotate, triple bonds have only a single carbon atom at each end

Formula

Question 26

Structural isomers have the same number of

Answer 26

Cs and Hs
