Question

The molecular formula of

pentane is C5H12. Which is the
molecular formula of an isomer of pentane? A. C5H12 B. C5H10 C. C5H12O D. C4H10

Answer 1

C5H12

Step-by-step explanation:

Isomers, by definition, have the same chemical formula. So, an isomer of pentane, which as a chemical formula of C5H12, would also have a chemical formula of C5H12. An example of an isomer of pentane would be 2 methyl butane.
