Question

Which of the following statements about alkynes is incorrect?

Alkynes are unsaturated hydrocarbons.


Alkynes have triple bonds.


Alkynes are saturated hydrocarbons.


Alkynes have carbon atoms.

Answer 1

The incorrect statement about alkynes is that they are saturated hydrocarbons. Alkynes are actually unsaturated hydrocarbons because they have one or more triple bonds between carbon atoms.

Step-by-step explanation:

The incorrect statement about alkynes is that they are saturated hydrocarbons. Alkynes are actually unsaturated hydrocarbons because they have one or more triple bonds between carbon atoms. They are not saturated because they can form additional bonds with other atoms or functional groups.

Answer 2

Alkynes are saturated hydrocarbons

Step-by-step explanation:

Alkynes are groups of hydrocarbons that have the general formula of {Cn H2n - 2}. They have a triple carbon to carbon bond (C≡C) in their structure. Ethyne (HC≡CH) is the first member of the alkyne series.

Alkynes like alkenes are unsaturated hydrocarbons because of their triple and double carbon bonds respectively. Unsaturated hydrocarbons do not have a complete hydrogen atom in their structural composition. Hence, the statement that "Alkynes are saturated hydrocarbons" is FALSE.
