a)

Interpretation Introduction

Interpretation:

  • The rate determining step of the given reaction has to be predicted.

Concept Introduction:

Reactions of conjugated dienes:

An electrophilic addition reaction to a conjugated diene forms both 1,2-addition and 1,4-addition products because the resonance contributors of the allylic cation give cation carbon and the chances for the nucleophile to attack at the electrophilic centre will occur.

Kinetic and thermodynamic products:

Kinetic product: The more rapidly formed product is called the kinetic product.  The reactions that produce the kinetic product as the major product are said to be kinetically controlled.  The kinetic product predominates when the reaction is irreversible.

Thermodynamic product: The more stable product is called the thermodynamic product.  The reactions that produce the thermodynamic product as the major product are said to be thermodynamically controlled.  The thermodynamic product predominates when the reaction is reversible.

Rule: The stabilities of carbocation are,

Benzyl cation = allyl cation = 3carbocation > 2 carbocation > 1 carbocation > methyl cation > vinyl cation

Calculate equilibrium concentrations for the following reaction:N2 (g) + O2 (g) ⇋ 2 NO (g) Kc = 0.10 at 2273K initially [N2] = 0.200M; [O2] = 0.200
For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3solution, the solution is basic (pH ~10), and the color is       ["", "", "", "", ""]  . At the equivalence point for the titration, the moles of added HCl are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCl begins to titrate the thymol blue indicator itself.  At the endpoint, the indicator color is       ["", "", "", "", ""]  . When you weren't paying attention and added too much HCl (~12 mL extra), the color is      ["", "", "", "", ""]  . When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is
