Chapter 20, Problem 25P

Interpretation Introduction

Interpretation:

The lethal doses of diquat dibromide and paraquat need to be calculated for a person weighing 56 kg

Concept introduction:

  • Toxicity is defined as the amount of a particular substance that can damage an organism
  • Lethal dose is denoted by LD50 which is the amount of material that can kill 50% of the population
  • It is expressed in terms of the amount of the toxic substance per kilogram of the body weight of the organism affected

13.84. Chlorine atoms react with methane, forming HCI and CH3. The rate constant for the reaction is 6.0 × 107 M¹ s¹ at 298 K. When the experiment was run at three other temperatures, the following data were collected: T (K) k (M-1 s-1) 303 6.5 × 107 308 7.0 × 107 313 7.5 x 107 a. Calculate the values of the activation energy and the frequency factor for the reaction. b. What is the value of the rate constant in the lower stratosphere, where T = 218 K?
My Organic Chemistry textbook says about the formation of cyclic hemiacetals, "Such intramolecular reactions to form five- and six-membered rings are faster than the corresponding intermolecular reactions.  The two reacting functional groups, in this case OH and C=O, are held in close proximity, increasing the probability of reaction."According to the book, the formation of cyclic hemiacetals occurs in acidic conditions. So my question is whether the carbonyl group in this reaction reacts first with the end alcohol on the same molecule or with the ethylene glycol.  And, given the explanation in the book, if it reacts first with ethylene glycol before its own end alcohol, why would it?  I don't need to know the final answer.  I need to know WHY it would not undergo an intermolecular reaction prior to reacting with the ethylene glycol if that is the case.  Please do not use an AI answer.
