Answer: Option (B) is the correct answer.
Explanation:
A change which brings change in composition of atoms of a substance to result in the formation of new substances is known as a chemical change.
Therefore, in a chemical change new substances are formed which have different properties as compared to their reactants.
For example, 
Thus, we can conclude that during all chemical changes atoms rearrange to form new substances.

Answer:
2–methyl–2–propanol.
Explanation:
To name the compound given in the question above, we must:
1. Identify the functional group and it's location on the compound.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound.
3. Identify the substituent group attached to the compound.
4. Locate the position of the substituent group.
5. Combine the above to obtain the name of the compound.
Thus, we can obtain the name of the compound as follow:
1. The functional group of the compound is alkanol (alcohol). It is located at carbon 2.
2. The longest continuous carbon chain is 3. Since the compound is an alcohol, parent name of the compound will change from propane to propanol.
3. The substituent group attached to the compound is methyl i.e –CH3.
4. The methyl group is located at carbon 2.
5. The name of the compound is
2–methyl–2–propanol.
