(a)
Interpretation:
Condensed formula for 2-hexyne has to be drawn.
Concept Introduction:
Organic compounds can be drawn from its IUPAC name. Initially, the parent chain is identified from the IUPAC name. After that the carbon chain is drawn with carbon atoms alone. Next step is to add the substituents in the respective positions as indicated in the IUPAC name. Remaining valency of carbon atom is satisfied by adding correct number of hydrogen atoms.
Condensed structural formula is a simplified form of representation of a molecule. This gives the information about all the atoms present in molecule and the atoms are placed in sequential order which gives information about which atom is bonded to other atom.
(b)
Interpretation:
Condensed formula for 4-methyl-1-pentyne has to be drawn.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Condensed formula for 1-chloro-4,4,5-trimethyl-2-heptyne has to be drawn.
Concept Introduction:
Refer part (a).
(d)
Interpretation:
Condensed formula for 2-bromo-3-chloro-7,8-dimethyl-4-decyne has to be drawn.
Concept Introduction:
Refer part (a).
