Write the condensed structural formulas for all distinct products that form by free radical monochlorination of 2,3-dimethylbutane. Knowing that tertiary hydrogen atoms react with a chlorine radical about 5.5 times faster than the primary ones, what percentage of each product would you expect after the reaction goes to completion

Ineed ! i have no clue how to do this problem.

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.

What is the measured amount of a product obtained from a chemical reaction?
