Which of the following is a second chain propagation step in the free radical chlorination of ethane? A. Cl· + Cl· + hv → Cl2 B. CH;CH2• + •CI → CH3CH2CI O C. Cl2 → 2Cl· D. CH3CH2• + Cl2 → CH3CH2CI + Cl• O E. CH3CH2 •+ • CH2CH3 CH2CH3 - CH3CH2CH2CH3

Why is this reaction considered "green" chemistry and how is it different from a "non-green" bromination? Based on this is this reaction completely "green" chemistry

The following is a nucleophilic substitution reaction of S-3-chloro-2-methylhexane with "CN. The experimental rate law for this reaction is Rate k [S-3-chloro-2-methylhexane] CH3 H;C. C. C H. CH3 CEN H2 H. The mechanism for this reaction is SN1 Draw the orgamic molecule(s) which is(are) formed in this reaction. Do not include molecules like H,O or HCl. Draw the specific configuration (R or S) at any chiral carbons within your product(s). If both configurations are formed in the product(s), draw both as separate molecules/products.

Below is the equation for a nucleophilic substitution reaction and some experimental data. CH3CH2Br + CH3COO- ⇌ CH3CH2CO2CH3 + Br- ΔH=-75 kJ/mol Rate = k [CH3CH2Br][CH3COO-] Which reaction energy profile would be the best representative of the data provided?

Question 3

Nucleophilic Substitution and Elimination. A Worksheet Lab. Pre-Lab 1. Identify the following organic transformations. Are they "substitutions" or "additions" or "eliminations"? Write formulas that clearly illustrate you selection. Pay attention to the organic part of the transformations. Example. Br ultraviolet light HBr + Br₂ formulas: CsH12 Br2 CsH11Br HBr This is a "substitution" reaction. H has been replaced (substituted) by Br

Ultraviolet, visible, infrared and nuclear magnetic resonance spectroscopies are among the types of spectroscopy that can be used to determine a reaction rate over time.  Consider the reaction of propene with bromine.  Bromine is a red-orange color.  The product of this reaction is 1,2-dibromopropane, a colorless compound.  Over the course of the reaction, bromine's color will ___________.   decrease    increase    remain the same    cannot be determined from information provided.
