Question

using what you learned about chemical structures on the last screen, which elements do you see in these four molecules? enter your answers using the atomic symbols shown in the diagrams (do not include spaces or commas).

Explanation:

Step1: Identify elements in the first molecule

In the first molecule, we can see \(C\) (from \(CH_2OH\)), \(H\) (from \(CH_2OH\) and \(OH\)), \(O\) (from \(OH\) and the oxygen - containing ring structure).

Step2: Identify elements in the second molecule

In the second molecule, we have \(C\) (in the carbon - chain structure), \(H\) (in \(HS\), \(NH_2\) and the carbon - chain), \(O\) (in \(OH\) and the carbonyl group \(C = O\)), \(N\) (in \(NH_2\)), \(S\) (in \(HS\)).

Step3: Consider common elements

Since we are looking for elements in all four molecules (assuming the third and fourth molecules also contain \(C\), \(H\), \(O\) as common elements in organic molecules. And from the first two molecules, we can confirm the presence of \(C\), \(H\), \(O\), \(N\), \(S\)).

Answer:

\(CHONS\)
