|Organic - Alkynes|
Alkynes are compounds which have low polarity, and have physical properties that are essentially the same as those of the alkanes and alkenes.
- They are insoluble in water.
- They are quite soluble in the usual organic solvents of low polarity (e.g. ligroin, ether, benzene, carbon tetrachloride, etc.).
- They are less dense than water.
- Their boiling points show the usual increase with increasing carbon number.
- They are very nearly the same as the boiling points of alkanes or alkenes with the same carbon skeletons.1

Alkyenes are hydrocarbons that have a carbon-carbon triple bond present.
Real World Application
Discover processes or disciplines in the natural or man-made worlds that employ the concept.
Polynes have been isolated from a wide variety of plant species, cultures of higher fungi, bacteria, marine sponges, and corals. They are also used in pharmaceuticals, for example Norethynodrel, a contraceptive. Other examples include calicheamicin, which is an aggressive antitumor drug. It is so powerful, sometimes it is known as “warhead”.2
