Chapter 13, Problem 28P

(a)

Interpretation Introduction

Interpretation:

The major product obtained on treating the compounds in problem 29 with Br2 at 125°C should be identified.

Concept introduction:

Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.

Bond strength is depends on the formation of the radical, if the radical is involving in resonance which is weakest bond strength.

Bromination:

Organic Chemistry, Chapter 13, Problem 28P , additional homework tip  1

1-Methyl cyclohexane is undergoes radical bromination which forms 1-bromo-1-methyl cyclohexane therefore, bromination will occur where the tertiary radical is present. Because bromination will occur selectively in tertiary alkyl radical. (bromination reactions are more selective reaction)

A block of zinc has an initial temperature of 94.2 degrees celcius and is immererd in 105 g of water at 21.90 degrees celcius. At thermal equilibrium, the final temperature is 25.20  degrees celcius. What is the mass of the zinc block? Cs(Zn) = 0.390 J/gxdegrees celcius Cs(H2O) = 4.18 J/gx degrees celcus
Potential Energy (kJ) 1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction. AH = -950 kJ AH = 575 kJ (i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s) Ea = 1550 kJ (ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s) (iii) Cl (g) + CICO (g) → Cl₂CO (g) Ea = 2240 kJ Ea = 2350 kJ AH = -825 kJ 2600 2400 2200 2000 1800 1600 1400 1200 1000 a. Draw the potential energy diagram for the reaction. Label the data points for clarity. The potential energy of the reactants is 600 kJ 800 600 400 200 0 -200- -400 -600- -800- Reaction Progress
