Flashcards in HChem Hydrocarbon Test Deck (26):
1

What types of hydrocarbons are saturated

Alkanes and cycloalkanes

2

Which types of hydrocarbons are unsaturated

Alkenes, Alkynes, cycloalkenes

3

What does it mean to be saturated

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

4

An organic compound consisting entirely of of hydrogen and Carbon.

Hydrocarbon

5

What is the general formula for Alkanes

2n+2

6

What is the general formula for alkenes

2n

7

What is the general formula for cycloalkanes

2n

8

What is the general formula of alkynes

2n-2

9

What is the general formula for cycloalkenes

2n-2

10

Cycloalkenes are (saturated/unsaturated)

Unsaturated

11

In cyclo, the ring assumes the long chain position
True or false

True

12

What are the prefixes used to name chains

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

13

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

Alphabetical

14

Start off with the ____ number

Lowest

15

What is the least reactive hydrocarbon

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

16

When you have a ring, make sure you put ___

Cyclo

17

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

Chloro, fluoro, bromo, iodo

18

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

True

19

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

Through

20

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

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

21

What does it mean for a hydrocarbon to be saturated

They only have single bonds

22

Why does water not mix with liquid hydrocarbons

Hydrocarbons are nonpolar and water is polar
These two will not mix together

23

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

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

24

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

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

25

Geometric isomers have the same word ___

Formula

26

Structural isomers have the same number of

Cs and Hs
