What would be the product if dimethyl maleate was heated in the presence of 3-sulfolene?

An organic reaction between a substituted alkene and a conjugated diene to form a substituted cyclohexene derivative is said to be Diels-Alder reaction (specifically, [4+2 cycloaddition). The formation of new -bonds is the driving force of this reaction, which is energetically more stable than the -bonds.

The reaction that takes place due to the heating of dimethyl maleate in presence of 3-sulfolene is as shown in the image.

On heating 3-sulfolene the compound breaks down to give sulfur dioxide gas and butadiene. This diene then reacts with dimethyl maleate which acts as a dienophiles and then these two diene and dienophiles will undergo a Diels-Alder reaction to form a new 6-membered cyclohexene ring.

Thus, the product formed due to the heating of dimethyl maleate in presence of 3-sulfolene is dimethyl cyclohex-4-ene-1,2-dicarboxylate.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
