Consider the given structure of the product of a Diels-Alder reaction. Ring made up of six carbons with a double bond between carbons 1 and 2 and a chlorine on both carbons 4 and 5. The two chlorines are on the same side of the ring. What reactants are necessary to make the product

See explanation below

Explanation:

First of all, a Diels Alder reaction is very useful to synthetize rings of 6 carbons. In order to do this, we need two reactants. A dienophile and a conjugate diene.

The conjugate diene, is usually a 4 or 5 carbons, with two double bonds, both conjugate and the dienophile, usually have one double bond and an withdrawing atractor group on 1 carbon.

We already have the product here, which is a ring of 6 carbons, with a double bond and chlorine in two carbons. The only way to do this is putting a conjugate diene of 4 carbons, and a dienophile with 3 carbons and 2 chlorines.

The mechanism of reaction is in the attached picture.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
