1
Q

What types of hydrocarbons are saturated

A

Alkanes and cycloalkanes

2
Q

Which types of hydrocarbons are unsaturated

A

Alkenes, Alkynes, cycloalkenes

3
Q

What does it mean to be saturated

A

Containing the greatest possible number of hydrogen atoms, and so having no carbon-carbon double or triple bonds

4
Q

An organic compound consisting entirely of of hydrogen and Carbon.

A

Hydrocarbon

5
Q

What is the general formula for Alkanes

A

2n+2

6
Q

What is the general formula for alkenes

A

2n

7
Q

What is the general formula for cycloalkanes

A

2n

8
Q

What is the general formula of alkynes

A

2n-2

9
Q

What is the general formula for cycloalkenes

A

2n-2

10
Q

Cycloalkenes are (saturated/unsaturated)

A

Unsaturated

11
Q

In cyclo, the ring assumes the long chain position

True or false

A

True

12
Q

What are the prefixes used to name chains

A

Meth, eth, prop, but, pent, hex, hept, oct, non, dec

13
Q

Make sure to put your types of bonds in ____ order, excluding number type prefixes (di, tri, tetra)

A

Alphabetical

14
Q

Start off with the ____ number

A

Lowest

15
Q

What is the least reactive hydrocarbon

A

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

16
Q

When you have a ring, make sure you put ___

A

Cyclo

17
Q

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

A

Chloro, fluoro, bromo, iodo

18
Q

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

A

True

19
Q

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

A

Through

20
Q

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

A

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

21
Q

What does it mean for a hydrocarbon to be saturated

A

They only have single bonds

22
Q

Why does water not mix with liquid hydrocarbons

A

Hydrocarbons are nonpolar and water is polar

These two will not mix together

23
Q

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

A

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

24
Q

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

A

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

25
Q

Geometric isomers have the same word ___

A

Formula

26
Q

Structural isomers have the same number of

A

Cs and Hs
