When a cyano group is joined to hydrogen, it forms hydrogen cyanide hydrogen cyanide, HCN, colorless, volatile, and extremely poisonous chemical compound whose vapors have a bitter almond odor. It melts at −14°C; and boils at 26°C;. It is miscible in all proportions with water or ethanol and is soluble in ether. ..... Click the link for more information. .

Structurally, a key difference between type I and type II pyrethroids is the absence or presence, respectively, of a cyano group at the [alpha] carbon of the 3-phenoxybenzyl alcohol moiety of the compound. However, it is clear that in the P1 structure the intermolecular distance between the cyano groups in neighbouring molecules in the [011] direction is too short (2. constituents, the cyano group of HNBR may be converted to an |
