B only has 4 Carbon molecules
D only has 9 Hydrogen molecules, therefore the answer is C – 5 Carbons, 12 Hydrogens and 1 Oxygen as the compound MTBE

In the question above, MTBE has chemical formulae as C5H12O. chemical formulae of the choices: A) C5H10O B) C4H10O C) C5H12O D) C5H10O So the answer must be (C). Cheers Sean Founder & Master Trainer SimpleChemConcepts.com Formally, Isomers are defined as substances that have the same chemical / molecular formulae but different structural formulae.

In the question above, MTBE has chemical formulae as C5H12O.

chemical formulae of the choices:
A) C5H10O
B) C4H10O
C) C5H12O
D) C5H10O

So the answer must be (C).
