The image provided shows the full reaction and the products of the reaction.
By heating 3-sulfolene, the compound breaks down into SO₂ gas and butadiene. The diene then reacts with the fumarate which is a dienophiles and these two species then undergo a Diels-Alder reaction. The diene reacts with the alkene portion of the fumarate and forms a new 6-membered cyclohexene ring. Since we have trans-fumarate, that leads to two potential products. We form a stereoisomer with stereocenters (1S, 2S) and another with stereocenters (1R, 2R). These two isomers formed are enantiomers. Therefore, the overall product is a racemic mixture of the two enantiomers.
While each individual enantiomer is optically active, the overall product would be racemic and therefore, not optically active.
If in the following diagram the substance is in the solid state during stage 1, during stage 2 the substance is boiling or condensing .
Boiling<span> is the term used to describe the rapid vaporization of a liquid. Boiling occurs when a liquid is heated to its </span>boiling<span> point.
</span>Condensation happens when the gas is changed into liquid.
Answer:
2.22 × 10^-5M
Explanation:
From Beer-Lambert's law;
A=εcl
Where A = absorbance of GMP= 0.2
ε= molar extinction coefficient of GMP = 9000 M-1cm-1
c= concentration of GMP= the unknown
l= path length = 1 cm
c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm
c= 2.22 × 10^-5M
