c. 3

d. 2

Explanation:

How many constitutionally isomeric monochlorination products are possible from the following?

a. 2-Methylpentane

In 2-methylpentane, there are five possible monochlorinated substitutional products in the reaction of chlorination of 2-methylpentane in the presence of sunlight.

b. In 3-methylpentane there are four possible monochlorinated substitutional products in the reaction of chlorination of 3-methylpentane in the presence of sunlight.

c. In 2,2-Dimethylbutane there are three possible monochlorinated substitutional products in the reaction of chlorination of 2,2-Dimethylbutane in the presence of sunlight.

d. In 2,3-Dimethylbutane there are two possible monochlorinated substitutional products in the reaction of chlorination of 2,3-Dimethylbutane  in the presence of sunlight.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
