Propose an experimental procedure that could be utilized to synthesize 1,2-dimethylcyclopentene from 1,2-dimethylcyclopentanol. Explain what minor product(s) might be expected by this method?
A compound is 42.9% C, 2.4% H, 16.7% N, and 38.1% O, by mass. Addition of 6.00 grams of this compound to 50.0 ml benzene, C6H6 (d = 0.879 g/mL), lowers the freezing point from 5.53 to 1.37 degrees celsius. What is the molecular formula of this com..
An experiment requires 43.0 of ethylene glycol, a liquid whose density is 1.114 . Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
