Consider the following hypothetical reaction which could occur between a cyclic haloalkane and magnesium hydride: C10H14Cl6 + Mg2H4 → C10H22Cl2 + Mg2Cl4 calculate the atom economy of this reaction assuming that C10H22CL2 is the desired product

Solutions

Expert Solution

Atom economy = ( molar mass of the desired product / molarmass of all the reactants ) x100

Molar mas of C₁₀H₂₂Cl₂ = (10xAt.mass of C ) + (22xAt.mass of H ) + (2xAt.mass of Cl)

= ( 10 x12) + (22x1) + (2x35.5)

= 213 g/mol

Molar mass of C₁₀H₁₄Cl₆ = (10xAt.mass of C ) + (14xAt.mass of H ) + (6xAt.mass of Cl)

= ( 10 x12) + (14x1) + (6x35.5)

= 347 g/mol

Molar mass of Mg2H4 = (2xAt.mass of Mg) + (4xAt.mass of H)

= (2x24) + (4x1)

= 52 g/mol

So total molar mass of the reactants = 347+52 = 399 g/mol

So atom economy = ( 213 / 399 ) x 100

= 53.4 %

Therefore the atom economy of this reaction is 53.4%

Distinguishing between an electrochemically reversible and irreversible electrode reaction can be done using cyclic voltammetry. Describe clearly and in detail how you can convert a fully reversible O/R electrochemical reaction into a irreversible or quasireversible reaction by varying parameters used in the CV experiment. Explain the reasoning behind your answer, and show using graphs how you would confirm that you have converted the reversible reaction into an irreversible one.
