Question

g Alkenes and alkynes are called unsaturated compounds because ________. they have fewer hydrogen atoms attached to the carbon chain than alkanes they have fewer carbon atoms than alkanes they have the maximum number of hydrogen atoms attached to each carbon in the compound they have more carbon atoms than alkanes they have more hydrogen atoms attached to the carbon chain than alkanes

Answer 1

Answer:

They have fewer hydrogen atoms attached to the carbon chain than alkanes

Explanation:

Let's compare ethane (an alkane) with ethene (an alkene) and ethyne (an alkyne):

• Ethane's formula is C₂H₄, while ethene's is C₂H₄ and ethyne's C₂H₂.

As you can see, alkenes and alkynes have fewer hydrogen atoms attached to the carbon chain due to them having multiple bonds between the carbon atoms.
