Concept Introduction:
Hydrocarbons are the organic compounds that contain only hydrogen and carbon atoms. Hydrocarbon derivatives are the one in which the compounds contain hydrogen and carbon atoms along with one or more additional elements. The additional elements that can be present in hydrocarbon derivatives are oxygen, nitrogen, sulphur, chlorine, bromine etc.

Considering the geometry of carbon atoms, the carbon atoms that have double bonds will have trigonal planar geometry. The carbon atoms that have only single bonds attached to it will have tetrahedral geometry. The carbon atoms that have a triple bond attached to it will have a linear geometry.
(a)

Answer to Problem 2.38EP
The spatial arrangement is identified as tetrahedral.
Explanation of Solution
Given structure is,
Looking into the left most carbon atom present in the given structure, it is not bonded to any double bonds or triple bond. This carbon atom has only four single bonds (three with hydrogen and one with carbon atom). Therefore, the spatial arrangement of the left-most carbon atom is tetrahedral.
The spatial arrangement of the left-most carbon atom is identified.
(b)
Interpretation:
The spatial arrangement for the chemical bonds in the left‑most carbon atom in the given structure has to be identified.

Hydrocarbon derivatives are the one in which the compounds contain hydrogen and carbon atoms along with one or more additional elements. The additional elements that can be present in hydrocarbon derivatives are oxygen, nitrogen, sulphur, chlorine, bromine etc.
Hydrocarbons are further classified into two categories. They are saturated hydrocarbons and unsaturated hydrocarbons. The hydrocarbons that contain single bonds between carbon atoms in the entire molecule is known as saturated hydrocarbon. The hydrocarbons that contain atleast one double or triple bond between two carbon atoms in the entire molecule is known as unsaturated hydrocarbon.
Saturated hydrocarbons are alkanes. Unsaturated hydrocarbons are alkene, alkyne and aromatic hydrocarbons.
