COMMON REACTIONS OF SATURATED HYDROCARBONS

Assume a single Br replacement in the reaction of methane and Br₂. Show the reaction between CH4 and Br2. CH4 + Br2 → CH3 +

Br HBr

Which of the following is not a halide hydrocarbon?

CH4

Why does chlorine react vigorously with hydrogen in the presence of sunlight?

Chlorine has a great attraction for hydrogen's electron

Which statement is true about the reaction between methane and chlorine?

They require ultraviolet light to react.

Calcium carbide and water react to form gas.

acetylene

The energy required to start a reaction is called _____.

activation energy

Balance the following reaction. C2H6 + Cl2 → C2H4Cl2 + HCl

When writing chemical formulas: Enter subscripts after the letters, for instance, H2O = Hs2O. Also, don't forget to use proper chemical shorthand for chemical symbols. For instance, chlorine = Cl but not cl or cL. When balancing equations: Leave the box empty if no other coefficient is needed. Writing the symbol implies "1." The halogen elements are all:

from Group VII

Select all that apply. How may the concentration of chloroform be increased as Cl2 gas reacts with CH2Cl2?

remove HCl from the product increase [Cl2]

Select all that apply. All the elements of the halogen family are very reactive because they:

require only one electron to complete their outer shell have a high electronegativity

What is the reaction type most typical of halides with saturated hydrocarbons?

substitution

What is the source of energy used to react chlorine with methane?

ultraviolet light
