Question

Question: Draw the products formed when a chlorine atom reacts with each species.

a.

b.

c.

d. O₂

Short answer

Answer

a.

b.

c.

d.

Step-by-step solution

Radical reaction

The radical atom abstracts the H atom from a C-H bond to form H-Cl and carbon radical. It also adds a bond to the C-C single bond. The radical can also react with its own form of cl₂ dimer.

Explanation of mechanisms in a and b

a.

Formation of products with a

When the Cl radical abstracts a proton from cyclohexane, it causes the cleavage of the C-H bond to form a carbon 2⁰radical and HCl.

b.

Formation of products with b

When chlorine radical adds to a double-bonded carbon, a 1⁰ carbon radical and a new C-C bond are formed.

 Step 3: Explanation of mechanisms in c and d

c.

Formation of products with c

Two chlorine radicals react with each other to form a cl₂ molecule.

d.

Formation of products with d

When a Cl radical reacts with O₂, it forms a single bond and new oxygen radicals
