,
, Hydrocarbon Classification & Fundamentals (Q1-10)
Q1: Define hydrocarbon.
A: Molecules composed only of the elements carbon and hydrogen.
Rationale: Hydrocarbons are the simplest organic compounds, containing
only C and H atoms. They form the foundation of organic chemistry.
Q2: What are the two major classes of hydrocarbon compounds?
A: Aliphatic Hydrocarbons (alkanes, alkenes, alkynes) and Aromatic
Hydrocarbons (benzene).
Rationale: This classification distinguishes between compounds with
single/double/triple bonds (aliphatic) and those containing a benzene ring
with delocalized electrons (aromatic).
Q3: What is the fundamental structural difference between alkanes,
alkenes, and alkynes?
A: Alkanes have only C-C single bonds (saturated). Alkenes have at least
one C=C. Alkynes have at least one C≡C.
Rationale: The type of carbon-carbon bond determines the saturation level
and reactivity of the compound. Alkanes are saturated; alkenes and alkynes
are unsaturated.
