Explain the TLC results you observed:
(a) Relate the Rf values for the two starting materials and the final product to their structures.
(b) The 2,4-hexadienol and the maleic anhydride were readily observed using the UV light. Explain why the product was only clearly observed after iodine staining (see example in Diels-Alder module on Canvas).

answer: i dont know the answer but this might

explanation:

l

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
