As Carbon is present in group 4, so it has 4 valence electrons, Hydrogen has 1 valence electron and Chlorine present in Group 7 has 7 valence electrons, Therefore, total number of electrons are,

                                C × 2  =  4 × 2  =  8

                                H × 5  =  1 × 5  =  5
 
                                Cl × 1  =  7 × 1  = 7

            Total Valence Electrons        = 20

The total number of valence electron In the Chloroethene [tex]\rm \bold{ (C_2H_5Cl)}[/tex] is 20.

In the Chloroethene [tex]\rm \bold{ (C_2H_5Cl)}[/tex]

  • Carbon is present in group 4, so it has 4 valence electron.
  • Hydrogen has 1 valence electron.
  • Chlorine present in Group 7 has 7 valence electrons.

C × 2  =  4 × 2  =  8

H × 5  =  1 × 5  = 5

Cl × 1  =  7 × 1  = 7

The total number of valence electron = 8 + 5+ 7 =20

Hence we can conclude that The total number of valence electron In the Chloroethene [tex]\rm \bold{ (C_2H_5Cl)}[/tex] is 20.
