4. Formular los siguientes hidrocarburos:
a) 4-metil-2-pentino; b) 3-propil-1,4-pentadiíno
Nomenclatura de alquinos
1) Un alquino es un hidrocarburo que tiene al menos un
triple enlace
2) Si tiene dobles y triples enlaces se denomina alquenino
3) La cadena principal es la más larga que contenga
insaturaciones (dobles o triples enlaces); si contiene
varias, es la que contiene más insaturaciones
4) Se citan primero los dobles enlaces
5) La cadena se numera de modo que los números más
bajos recaigan en las insaturaciones (sean dobles o triples
enlaces, aunque tienen preferencia los dobles en el caso
de dos numeraciones equivalentes)

Unsaturated branched acyclic hydrocarbons are named as derivatives of the unbranched hydrocarbons which contain the maximum number of double and triple bonds (http://www.acdlabs.com/iupac/nomenclature/79/r79_53.htm)
Unsaturated unbranched acyclic hydrocarbons having one triple bond are named by replacing the ending "-ane" of the name of the corresponding saturated hydrocarbon with the ending "-yne". If there are two or more triple bonds, the ending will be "-adiyne", "atriyne", etc. The generic names of these hydrocarbons (branched or unbranched) are "alkyne", "alkadiyne", "alkatriyne", etcThe chain is so numbered as to give the lowest possible numbers to the triple bonds. Only the lower locant for a triple bond is cited in the name of a compound.
