Question 1

What is an alkane molecule?

Answer 1

A molecule which contains a single bond between two carbon atoms.

Question 2

What is an alkene molecule?

Answer 2

A molecule which contains a double bond between two carbon atoms.

Question 3

What is an alkyne molecule?

Answer 3

A molecule which contains a triple bond between two carbon atoms.

Question 4

How do you name alkanes?

Answer 4

Find the prefix by finding the longest carbon chain in the alkane molecule - Then add the suffix “-ane”.

Question 15

How do you name an alkene molecule?

Answer 15

Find the longest chain of carbons to determine the prefix - Add the suffix “-ene” - Insert the position of the double both between the prefix and the suffix (Eth-1-ene)

Question 16

How do you name an alkyne molecule?

Answer 16

Find the longest chain of carbons to determine the prefix - Add the suffix “-yne” - Insert the position of the triple bond between the prefix and the suffix. (Hex-3-ene)

Question 17

How do you name side groups?

Answer 17

The number of carbons determines the prefix, the suffix will always be “-yl”. Name its position at the front of the molecule and place the name of the side group at the front of the molecules name.

Question 18

What does the term “Saturated” refer to?

Answer 18

A substance in which the atoms are linked by single bonds. A fully saturated compound will contain no double or triple bonds.

Question 19

What does the term “Unsaturated” refer to

Answer 19

A substance in which contains double and triple bonds between the atoms.

Question 20

What are Haloalkanes?

Answer 20

Similar to alkanes, haloalkanes have halogen atoms on its chain. These halogen atoms are the following: Fluorine (F), Chlorine (Cl), Bromine (Br), and Iodine (I).

Question 21

How would you name a Haloalkane?

Answer 21

The halogens location goes before the prefix. The prefix is determined by the halogen atom (F = Fluoro), The identification for the longest chain will go in the middle (Pent-) and the suffix will be -ane.

Question 22

If you have different halogen atoms in a compound, what’s the order you would name the halogens in?

Answer 22

In alphabetical order. For example, 7-Bromo-4-Chloro.

Question 23

If you have multiple of the same halogen atoms in a compound, what’s the order you would name these halogens in?

Answer 23

You would name them in carbon number order eg 1,2,3. And depending on the number of halogens add Di or Tri ect before the halogen name.

Question 24

What is the functional group of an alcohol molecule?

Answer 24

A hydroxyl group (-OH)
