In CH₃-CH₂-CH₂-Cl:
C1-H (3 bonds)
C1-C2 (1 bond)
C2-H (2 bonds)
C2-C3 (1 bond)
C3-H (2 bonds)
C3-Cl (1 bond)
Total = 3 + 1 + 2 + 1 + 2 + 1 = 10 covalent bonds.
In CH₃-CHCl-CH₃:
C1-H (3 bonds)
C1-C2 (1 bond)
C2-H (1 bond)
C2-Cl (1 bond)
C2-C3 (1 bond)
C3-H (3 bonds)
Total = 3 + 1 + 1 + 1 + 1 + 3 = 10 covalent bonds.
