Textbook QuestionThe chlorination of pentane gives a mixture of three monochlorinated products. b. Predict the ratios in which these monochlorination products will be formed, remembering that a chlorine atom abstracts a secondary hydrogen about 4.5 times as fast as it abstracts a primary hydrogen.1006views
Textbook QuestionGiven the ratio of products obtained in the bromination of propane, calculate the relative reactivity of a 1° C―H bond to a 2° C―H bond under these conditions.<IMAGE>342views
Textbook QuestionA chemist wanted to determine experimentally the relative ease of removing a hydrogen atom from a tertiary, a secondary, and a primary carbon by a chlorine radical. He allowed 2-methylbutane to undergo chlorination at 300 °C and obtained as products 36% 1-chloro-2-methylbutane, 18% 2-chloro-2-methylbutane, 28% 2-chloro-3-methylbutane, and 18% 1-chloro-3-methylbutane. What values did he obtain for the relative ease of removing a hydrogen atom from tertiary, secondary, and primary hydrogen carbons by a chlorine radical under the conditions of his experiment?501views
Textbook QuestionWhen 2-methylpropane is monochlorinated in the presence of light at room temperature, 36% of the product is 2-chloro-2-methylpropane and 64% is 1-chloro-2-methylpropane. From these data, calculate how much easier it is to remove a hydrogen atom from a tertiary carbon than from a primary carbon under these conditions.1535views

Textbook QuestionThe following are all substitution reactions, two of which we study in later chapters. With no knowledge of mechanism, what would you expect the ratio of products to be for each reaction, based on a random statistical distribution? (a) Replacing a hydrogen (H) with chlorine (Cl):361views
Textbook QuestionWhat would be the product ratio in the chlorination of propane if all the hydrogens were abstracted at equal rates?609views

Textbook QuestionThe deuterium kinetic isotope effect for the halogenation of an alkane is defined in the following equation, where X･ = Cl･ or Br･<IMAGE>Predict whether chlorination or bromination would have a greater deuterium kinetic isotope effect.429views
Textbook Question (••) Predict the product(s) of the following halogenation reactions. Only one equivalent of the halogen is used in each case. If the reaction proceeds selectively, indicate this by only drawing the major product. If the reaction is not selective, draw all possible products.(b) <IMAGE>318views
Textbook QuestionSuppose a 2-halobutane was needed for a synthetic sequence. Starting your synthesis with butane, would it be best to put a chlorine or bromine at that position? Explain.345views
Textbook QuestionAt 600 °C, the ratio of the relative rates of formation of a tertiary, a secondary, and a primary radical by a chlorine radical is 2.6 : 2.1 : 1. Explain the change in the degree of regioselectivity compared to what was found in Problem 44.383views
