Which option correctly defines an alkyne?
a hydrocarbon in which at least one carbon atom makes a triple bond
a hydrocarbon in which at least one carbon atom makes a bond with an oxygen atom
a hydrocarbon in which at least one carbon atom makes a double bond
a hydrocarbon in which at least one carbon atom makes a bond with a hydrogen atom
I think its A i'm not 100% sure i'm trying to take the test myself.
The correct option is: a hydrocarbon in which at least one carbon atom makes a triple bond.
To determine the correct definition of an alkyne, we need to understand the structure of alkanes, alkenes, and alkynes.
An alkane is a hydrocarbon in which carbon atoms are connected by single bonds. For example, methane (CH4) and ethane (C2H6) are alkanes.
An alkene is a hydrocarbon in which carbon atoms are connected by at least one double bond. For example, ethene (C2H4) is an alkene.
Now, let's consider the options provided:
1. A hydrocarbon in which at least one carbon atom makes a triple bond: This option correctly defines an alkyne. Alkynes contain at least one carbon-carbon triple bond. For example, ethyne (also known as acetylene, C2H2) is an alkyne.
2. A hydrocarbon in which at least one carbon atom makes a bond with an oxygen atom: This option does not describe an alkyne. It instead describes an alcohol, where a carbon atom is bonded to an oxygen atom.
3. A hydrocarbon in which at least one carbon atom makes a double bond: This option describes an alkene, not an alkyne. Alkynes are characterized by a carbon-carbon triple bond.
4. A hydrocarbon in which at least one carbon atom makes a bond with a hydrogen atom: This option describes an alkane, where carbon atoms are bonded to hydrogen atoms by single bonds.
Therefore, the correct definition of an alkyne is: "a hydrocarbon in which at least one carbon atom makes a triple bond."
