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).
Rating Newest Oldest. Best Answer: alcohols are acidic. the extent depends on the particular alcohol. exactly as yobbo states and devin, pop and beer are acidic due to carbonic acid. and Carol, hate to burst your bubble but... H-O-SO2-OH is sulfuric acid and contains OH groups. oh, and as to eyeball damage.it depends on the alcohol. Some, in dilute concentrations, probably wouldnt' do much damage.xactly as yobbo states and devin, pop and beer are acidic due to carbonic acid. and Carol, hate to burst your bubble but...
