C-4 (explosive) C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C. The British version of the explosive is known as PE-4 (Plastic Explosive). C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modeling clay and can be molded into any desired shape. C-4 is stable and an explosion can only be initiated by the combination of extreme heat and shock wave from a detonator.
The formyl group is a functional group, with the structure R-CHO, consisting of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group, which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group.ecause of resonance stabilization of the conjugate base, an Î±-hydrogen in an aldehyde (not shown in the picture above) is far more acidic, with a pKa near 17, than a C-H bond in a typical alkane (pKa about 50).
Aldehydes and Ketones When a primary (10) alcohol is oxidized, the product is an aldehyde, while a second (2 0) alcohol yield a ketone. The âCHO group of an aldehyde is easily oxidized to a carboxylic acid: ox.R--------CHO-------R---------COOH aldehyde carboxylic acid Ketones on the other hand, resist oxidation. This difference is the basis of several common laboratory tests that distinguish aldehydes from ketones.es â No â â acidic â neutral basic. An unknown is a ketone.Carboxylic acids are weaker acid than the mineral acid but are stronger acids than the alcohols and phenols. most probably a nail polish remover. we conclude that: 1. Benedictâs reagents are a weak oxidation agent that only reacts with aliphatic aldehydes.
