McMurry (Kap.3,2)

Question 1

What are alkanes?

Answer 1

By overlapping C-C single bonds in a chain, the family of alkanes are generated.

The overlap of a (SP3) Carbon with the overlap of another (SP3) carbon, which is a sigma bond.

Question 2

Why are alkanes descripted as saturated hydrocarbons?

Answer 2

Because they only have C-C and C-H single bonds, and thus contain the maximum possible number of hydrogens per carbon.

Question 3

Why are alkanes sometimes called “aliphatic compounds?”

Answer 3

Because many animal fats contain carbon chains similar to alkanes.

Question 4

What are the difference between “straight chain alkane” and “branched chain alkane”

Answer 4

Straight chain alkanes have their carbons connected in a row, whereas branched chain alkanes have some of their carbons connected to the row like branches.

Question 5

What is the term “isomers?” - more specifically “consitutional isomers”

Answer 5

Compounds that have the same formula, but different structures (ways the molecule is connected)

Question 6

Does the number of possible isomers rise as the number of C-atoms in a molecule rise?

Answer 6

Yes, the possible structural arrangements of a molecule rise as the number of C in the molecule rise.

Question 7

Hvad er “constitutional isomers?”

Answer 7

Forskellige consitutional isomers har forskellige forbindelser, med forskellige egenskaber men den samme kemiske formel/indhold.

Question 8

Which suffix is added to the end of the name, to illustrate that it is an alkane?

Answer 8

-ane

Question 9

What is the parent name of the 10 first alkanes?

Answer 9

1-methane
2-ethane
3-propane
4-butane
5-pentane
6-hexane
7-heptane
8-octane
9-nonane
10-decane

Question 10

What is the suffix ending to illustrate that the molecule is an alkyl? (for example the side chains bound to the alkane chain.).

Answer 10

-yl
