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.
An aldehyde /ËaeldÉ¨haÉªd/ ËÃ¦ldÉ¨haÉªd or alkanal is an organic compound containing a formyl. Group 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. chainecause 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).
An aldehyde /ËÃ¦ldáµ»haÉªd/ or alkanal is an organic compound containing a functional group with the structure âCHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain.
