Question

question 1 (1 point)
what type of organic reaction is the following:
but - 2 - ene + hcl -- >
oxidation
esterification
elimination
addition (hydrohalogenation)
question 2 (1 point)
what type of organic reaction is the following:
benzene + cl₂ -- >
reduction
substitution
elminination
condensation

Explanation:

For Question 1:

• Oxidation involves the loss of electrons or an increase in oxidation state.
• Esterification forms esters from carboxylic acids and alcohols.
• Elimination removes atoms or groups to form a double bond.
• Addition (hydrohalogenation) adds a hydrogen - halide to an alkene. But - 2 - ene is an alkene and HCl is a hydrogen - halide.

For Question 2:

• Reduction involves the gain of electrons or a decrease in oxidation state.
• Substitution replaces an atom or group in a molecule. Benzene undergoes substitution reactions with \(Cl_2\) (in the presence of a catalyst like \(FeCl_3\)) where a hydrogen atom is replaced by a chlorine atom.
• Elimination removes atoms or groups to form a double bond.
• Condensation forms a larger molecule with the loss of a small molecule (e.g., water).

Answer:

Question 1: addition (hydrohalogenation)
Question 2: substitution
