17
Q

Bromine

A

A chemical test used to distinguish between alkane and alkenes

18
Q

Primary alcohol

Secondary alcohol

Tertiary alcohol

A

When the carbon attached to the OH group is only attached to one carbon

When the carbon attached to the OH group is attached to two carbons

When the carbon attached to the OH group is attached to three carbons

19
Q

Primary halogeoalkane

Secondary halogenoalkane

Tertiary hogenoalkane

A

When the carbon attached to the halogen is only attached to one carbon

When the carbon attached to the halogen is attached to two carbons

When the carbon attached to the halogen is attached to three carbons

20
Q

Primary, secondary and
tertiary amines

A

The reasoning for amines is slightly different..
The focus is on the nitrogen atom in the amine
functional group
Nitrogen attached to two H and 1 carbon = primary
Nitrogen attached to 1 H and 2 C = secondary
Nitrogen attached to 3 C = tertiary
