1Determine which orbitals from each atom are used for the CH

1.Determine which orbitals from each atom are used for the C-H bonds and the C-C bonds according the the VBT(hybrid orbitals). C2H6 C2H4 C2H2.

2. Why does the distance decrease as the bond order of the C-C bond increases?

1.
C2H6= sp3

C2H4 = sp2

C2H2.= sp

2. Bond length is related to bond order, when more electrons participate in bond formation the bond will get shorter.
