Suggest an experimental process that could be used to synthesize 1, 2-dimethylcyclopentene from 1, 2-dimethylcyclopentanol. Explain what minor product(s) might be expected by this method? Provide the detailed reaction mechanism leading to the final product major. Explain what simple chemical test(s) would help establish that you had in fact made the desired alkenes product?
Gases azomethane decomposes in a first order reaction when heated: CH3NNCH3 --> N2 + C2H6. The rate constant is 0.0216 min-1. If the initial quantity of azomethane in the flask is 2.00 g, how much remains after 0.0500 hour
Draw (in increasing energy ordering) 3 different alkenes derived from the dehydration of 1,2-dimethylcyclohexanol
A is the sequence Na, Mg, Al, Si, and P. B is the sequence He, Ne, Ar, Kr, and Xe. Which statement below is true. The members of B are decreasing in size.
If the heat released during condensation goes only to warming the iron block, what is the final temperature (in C) of the iron block
Consider the four polysaccharides amylose, spartylose tarhylose and ranylose. Amylose is the unbranched polymer of a-(1Ã 4) linked glucose molecules found in starch, while spartylose, tarhylose and a Blue Devylosea
