Hidrocarbons practice

Look at the following hydrocarbon, choose what its name is

• 3-methyl, heptane

• 3-ethyl, octane

• 3-methyl, octane

• 3-ethyl, heptane

Look at the following hidrocarbon. Name the principal chain

remember: double and triple bonds must be included on the principal chain

the name of this hydrocarbon is 2,3 dimethyl-propane

• false, it´s a butene

• True

• False, it´s a pentane

• false, it is a butane

Based on this hidrocarbon, we can safely call the longest chain:

• octane

• octene

• octine

• decane

• Neither of the options

Answer explanation

The principal chain can´t ignore the double or triple bonds

look at the principal chain, then answer how many radicals are inside the structure

• Three methyl groups and an ethyl

• Two methyl groups and one ethyl

• A propyl group and one ethyl

• Two ethyls and a methyl

When we finally get to our desired principal chain, there are some carbons that are outside of it and must be named diferently. these are called:

Talking chemistry wise, this figure is a

• Propane

• propine

• cyclepropane

• Cyclopropine

• Cyclopropene

Think of a closed fogure with six sides. Math wise it would be called hexagon, Chemistry wise it´s name would be

The following figure is:

• an octane with an ethyl and three methyls

• a decane two methyls and thw ethyls

• an octene with four methyls and an ethyl

• an octine with 6 radicals

Make in your notebook a molecule that has 2 carbons and 2 hidrogens. thaking into consideration that carbons make 4 bonds and hidrogens 1, what would be the molecule´s name?
