Which of the Following Represents the Molecular Formula of a Noncyclic

Question

Which of the following represents the molecular formula of a noncyclic alkane?
A) C5H10
B) C6H12
C) C4H8
D) none of these

Accepted Answer

Noncyclic alkanes have the general molecular formula CnH2n+2, where n is the number of carbon atoms. None of the given formulas match this pattern, indicating that none of them represent a noncyclic alkane.
