what is the name of this molecule: ch₃ - ch₂ - ch₂ - ch(cl) - ch₂(cl)?
select the correct answer below:
1,2 - chloropentane
1,2 - dichloropentane
4,5 - chloropentane
4,5 - dichloropentane

Explanation:

The molecule has a 5 - carbon chain (pentane). There are two chlorine (Cl) atoms, one on the 1 - carbon and one on the 2 - carbon. The prefix 'di -' is used for two substituents of the same kind. The numbering of carbon atoms starts from the end that gives the substituents the lowest possible numbers.

Answer:

B. 1,2 - Dichloropentane
