◉ C3H7COOH. Answer: Butyric acid


◉ Classification of carbon atoms. Answer: Primary, secondary,
tertiary, quaternary carbon atom


◉ Primary carbon atom ( 1 degree ). Answer: A carbon atom
containing a functional group attached to only one other carbon
atom or bonded to 2-3 H-atoms.


◉ Secondary carbon atom (2 degree). Answer: A carbon atom
containing a functional group attached to two other carbon atoms or
bonded to 1-H atom.


◉ Tertiary carbon atom (3 degrees). Answer: A carbon atoms
contains a functional group attached to three other carbon atoms or
bonded to no H-atoms.


◉ Quaternary carbon atom (4 degree). Answer: A carbon atom
attached to four other carbon atoms.

,◉ IUPAC system. Answer: Nomenclature of compounds based on
structure.


◉ Parts of the IUPAC name of a compound. Answer: Root word,
suffix, prefix.


◉ Root word. Answer: It is the word which indicates the number of
carbon atoms present in the parent chain. It is the word which is
written in between the prefix and suffix.


◉ Parent chain. Answer: It is the chain of c-atoms in an organic
compound containing maximum number of c-atoms in it and
includes the principal functional group. Depending upon the number
of carbon atoms present, different root word is given.
