Expert Answer

Step 1

In first part of question we are asked to draw the 3-D sketch of Acetylene and ethylene and label the hybridization on each carbon atom.

The chemical of acetylene and ethylene are:

Ethylene = C2H4

Acetylene = C2H2

Step 2

In ethylene, two carbon atoms are bonded through a double bond (one sigma and one pie) and on each carbon atoms, 2 H-atom are attached.

Step 3

Here Carbon atoms are sp2  hybridize i.e., each carbon atom has 3 sp2 hybrid orbitals and 1p orbital in its valence subshell which are available for bonding.

The two carbon atoms are linked through double bond which has one sigma...
