Question

Write structural formulas for the following compounds (includes both old- and new-style names).

(a) 2-octyne (b) ethyl isopentyl acetylene (c) ethynylbenzene

(d) cyclohexyl acetylene (e) 5-methyl-3-octyne (f) trans-3,5-dibromocyclodecyne

(g) 5,5-dibromo-4-phenylcyclooct-1-yne (h) (E)-6-ethyloct-2-en-4-yne

(i) 1,4-heptadiyne (j) vinylacetylene (k) (S)-3-methyl-1-penten-4-yne

Short answer

The structural formula is the complete form of showing how the molecules in the compound are presented.

Structure formula is the complete representation of any chemical compound, and it is much more complex than condensed formula.
