8) In the reaction of Cl2 with ethane and UV light, which of the following reactions would be a propagation step(s)? I) Cl2 + CH3-CH3 → CH3-CH2-Cl + HCl II) CH3-CH3 + CH2-CH3 → CH3-CH2-CH2-CH3 III) CH3-CH2-Cl + HCl → CH3-CH2-CH2-Cl + H2 IV) Cl2 + CH2-CH3 → CH2-CH2-Cl + HCl V) Cl2 + UV light → Cl + Cl

Ethane (CH3CH3) reacts with chlorine (Cl2) in the presence of UV light by free radical substitution to form chloroethane (CH3CH2Cl) and HCl. Given the Bond Dissociation Energies below, calculate the enthalpy change (ΔH) for the first propagation step: Bond A-B ΔH Cl—Cl 58 CH3—H 104 CH3CH2—H 98 CH3CH3 88 CH3CH2—Cl 81 H—Cl 103 Select an answer and submit.

00:01 Here the reaction is that is ch3, ch3, that it reacts with the cl2 and it forms the term, that is ch3, cl2, that is ch2, cl, let's hcl.
00:14 This occurs in the presence of the uv light by the mechanism similar to the fluorination of the methane.
00:21 Let's write the mechanism.
00:23 That is first one is the chain initiation, chain initiation step.
00:30 And the next one is the chain propagation and the third one is the that is chain termination let's write the initiation step first the initiation would be like this that is 2 chlorine that is cl2 here cl2 this bond breaks and generates the radical that is 2 cl and the next is the formed radical get attached to the ch3 ch3 molecule and the next is propagation that is the formed radical is c.
01:26 Dot that get attached to the here's ch2, ch3, this is h, this get attached to the ch and this bone shifts here and generates the radical on the carbon and that would be ch2 radical plus ch3 plus hcl.
01:48 The cl get attached to the h and eliminates as a hcl and another one is that is again the cl molecule that is cl get reacts with the ch2, ch3...
