Vinyl chloride (C2H3C1) differs from ethylene (C2H4) in
Chapter 9, Problem 126P(choose chapter or problem)
Vinyl chloride \(\left(\mathrm{C}_2 \mathrm{H}_3 \mathrm{Cl}\right)\) differs from ethylene \(\left(\mathrm{C}_2 \mathrm{H}_4\right)\) in that one of the H atoms is replaced with a CI atom. Vinyl chloride is used to prepare poly(vinyl chloride), which is an important polymer used in pipes.
(a) Draw the Lewis structure of vinyl chloride.
(b) The repeating unit in poly(vinyl chloride) is - \(\mathrm{CH}{ }_2-\mathrm{CHCl}_{-}\). Draw a portion of the molecule showing three such repeating units.
(c) Calculate the enthalpy change when \(1.0 \times 10^3 \mathrm{~kg}\) of vinyl chloride forms poly(vinyl chloride).

ANSWER:Step 1 of 4
Lewis structures:
The bonding in the molecule can be understood by its structures, which involves the distribution of electrons around each atom and type of bonding (single, double, triple).
Lewis structure represents the electron distribution around atoms in the molecule, it is also known as electron - dot structures which have the following features.
- These structures take into account only valence electrons
- This clearly shows bonding and non bonding electrons.
- All atoms should obey the octet rule.
