Question

Find the compound methylene chloride on the internet.

a) Why do you think the name starts with the prefix “meth”? How does it relate to the structure of the compound?

b) List any other names you found for methylene chloride

c) What are the similarities between the names?

d) Methylene chloride does not dissolve well in water, but dissolves oily materials like tars and asphalt fairly well. Given what you know about intermolecular forces why might this be the case? Drawing the structure and thinking about the types of bonds will help you decide.

Explanation / Answer

a) meth = 1 carbon atom

Hence, methylene chloride = H2C-Cl2 (or) CH2Cl2

b) other names for methylene chloride = Dichloro methane

c) methylene chloride = H2C-Cl2 (or) CH2Cl2

Since methylene chloride is an organic compound , it is dissolved well in organic solvents like tars and asphalt.

''Like dissolves like"

Water is a polar compound.

C-H bond in CH2Cl2 in non-polar but C-Cl bond is polar. Hence, the CH2Cl2 is not that much polar.

Therefore,

Methylene chloride does not dissolve well in water.
