D
Verified step by step guidance1
Identify the structure of the disulfide compound shown in the first image. It consists of two ethyl groups (CH3CH2-) connected by a disulfide bond (S-S).
Understand that disulfides are formed by the oxidation of thiols. Each thiol contributes one sulfur atom to the disulfide bond.
Examine the thiol structures provided in the subsequent images. Look for a thiol that, when two molecules are combined, would result in the disulfide structure identified in step 1.
The first thiol image shows a structure with an ethyl group attached to a thiol group (CH3CH2SH). This matches the ethyl groups in the disulfide structure.
Conclude that the thiol in the first image (CH3CH2SH) is the one that, upon oxidation, will produce the disulfide shown in the first image.
