Question

Which of the following are hydrocarbons? Check all that apply.

a) A. A chain of 5 carbons with upper (Cₗ) at the end.
b) B. Two central carbons bonded to (CH₃) at each end, and also to the first of the 2 central carbons.
c) C. A carbon is double-bonded to an (O) above and to (2HC₃) below.
d) D. (2) carbons are triple-bonded to each other, each with an (H) to the outside.

Answer 1

The hydrocarbons in the options are: A chain of 5 carbons, Two central carbons bonded to (CH3), and (2) carbons triple-bonded to each other.

Step-by-step explanation:

Hydrocarbons are organic compounds composed of carbon and hydrogen atoms. They are classified based on the types of bonding between carbon atoms.

The hydrocarbons in the options are:

• A. A chain of 5 carbons with upper (Cl) at the end is an alkane because it only contains single carbon-to-carbon bonds.
• B. Two central carbons bonded to (CH3) at each end, and also to the first of the 2 central carbons represents an alkene because it contains a double bond between the carbon atoms.
• D. (2) carbons triple-bonded to each other, each with an (H) to the outside is an alkyne because it contains a triple bond between the carbon atoms.
