How many different aldehydes have the molecular formula C₄H₈O? A) 1 B) 2 C) 3 D) 4

Question

Quizplus · Accepted Answer

The molecular formula indicates the presence of 1 carbon (C1) atom, 1 sulfur (S1) atom, 1 hydrogen (H1) atom, and 18 oxygen (O18) atoms, along with 2 unidentified atoms (U1B14 and U1B0). Since aldehydes are compounds that contain a carbonyl group (C=O), the U1B14 atom is most likely carbon, which would make the compounds aldehydes. However, since there are only 1 carbon atom present, there can only be 2 different aldehydes: form aldehyde (H-C=O) and thioformaldehyde (H-CS=O). Therefore, the answer is B (2).
