How many monochloro constitutional isomers would the reaction of 2-methylbutane with chlorine in the presence of light produce?

There are 4 monochloro isomers possible

Explanation:

The monochlorination of 2-methyl butane has 4 monochloro isomers, with different grade of abundance.

33 % 2-chloro-3-methylbutane

30 % 1-chloro-2-methylbutane

22 % 2-chloro-2-methylbutane

15 % 1-chloro-3-methylbutane.

33 % 2-chloro-3-methylbutane  is the most stable; 15 % 1-chloro-3-methylbutane is the less stable.

Of those 4 monochloro isomers, there are two chiral compounds  possible

⇒ 2-chloro-2-methylbutane

⇒ 2-chloro-3-methylbutane.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
