Chapter 2.4: Cycloalkanes

Question 1

What is a saturated hydrocarbon that contains carbons joined to form a ring?

Answer 1

cycloalkane

Question 2

What is the formula for a cycloalkane?

Answer 2

o Cycloalkanes contain two fewer hydrogen atoms than an alkane with the same number of carbon atoms and have the general formula CnH2n

Question 3

What do you do  If there is only one substituent on the cycloalkane ring?

Answer 3

 If there is only one substituent on the cycloalkane ring, there is no need to give it a number

Question 4

What do you do  If there are three or more substituents on a cycloalkane ring?

Answer 4

 If there are three or more substituents, number the ring and substituents the lowest set of numbers and list them in alphabetical order

Question 5

How do you name a cycloalkane?

Answer 5

o To name a cycloalkane, prefix the name of the corresponding open-chain alkane with cyclo- and name each substituent on the ring

Question 6

Define bicycloalkane

Answer 6

an alkane containing two rings that share two carbons

Question 7

Define cyclalkane

Answer 7

a saturated hydrocarbon that contains carbons joined to form a ring

Question 8

Describe the carbons in a bicycloalkane

Answer 8

 The shared carbon atoms are called bridgehead carbons, and the carbon chain connecting them is called a bridge

Question 9

What is an alkane containing two rings that share two carbons?

Answer 9

bicycloalkane

Question 10

What do you do  If there are two substituents on a cycloalkane ring?

Answer 10

 If there are two substituents, number the ring by beginning with the substituent of lower alphabetical order

Question 11

What is a cyclic hydrocarbon?

Answer 11

• A hydrocarbon that contains carbon atoms joined to form a ring is called a cyclic hydrocarbon
