Structure and general properties. Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. [citation needed] HCN has a faint bitter almond -like odor that some people are unable to detect owing to a recessive genetic trait. [13] The volatile compound has been used as ...
Pacemaker current. The pacemaker current ( If, or IKf, also called funny current) is an electric current in the heart that flows through the HCN channel or pacemaker channel. Such channels are important parts of the electrical conduction system of the heart and form a component of the natural pacemaker . First described in the late 1970s in ...
Hydrocyanation. In organic chemistry, hydrocyanation is a process for conversion of alkenes to nitriles. The reaction involves the addition of hydrogen cyanide and requires a catalyst. This conversion is conducted on an industrial scale for the production of precursors to nylon.
In organic synthesis, cyanide, which is classified as a strong nucleophile, is used to prepare nitriles, which occur widely in many chemicals, including pharmaceuticals. Illustrative is the synthesis of benzyl cyanide by the reaction of benzyl chloride and sodium cyanide.
In the nervous system, heart, and some visceral organs, cells contain cyclic nucleotide gated channels which determine the rhythm of the organ. These channels, formally called hyperpolarization-activated cyclic nucleotide–gated channels (HCN channels), are also termed "pacemaker channels" because of this critical function. As their name ...

Following the sale of one of Diana’s evening dress for more than $1.1 million in December, co-founder of Julien’s Auctions Martin Nolan said on the "TODAY" show Monday that interest in selling ...
Neutralization (chemistry) Animation of a strong acid–strong base neutralization titration (using phenolphthalein ). The equivalence point is marked in red. In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react with an equivalent quantity of each other.
