Question

A saturated straight-chain hydrocarbon with two carbons is ____.

Answer 1

A saturated straight-chain hydrocarbon with two carbons is ethane (СH₃-CH₃).

Answer 2

A saturated sraight-chain hydrocarbon with two carbons is ethane.

Step-by-step explanation:

Saturated hydrocarbons are called as alkanes with general formula
`C_(n)H_(2n+2)` where n=1,2,3,4......

Now, as it contains two carbon atoms therefore name of this compound should contain a prefix "eth". Also a suffix "ane" will come due to the fact that it is a saturated hydrocarbon.

So, molecular formula of this compound is
`C_(2)H_(6)`

Structure of this straight chain compound has been attached below.
