Is cubane an explosive?

Is cubane an explosive?

As molecular volume is (very roughly) a group additive property, highly nitrated cubanes can be predicted to be very dense – and hence to be very powerful explosives.

What is cubane used for?

Having high potential energy but kinetic stability makes cubane and its derivative compounds useful for controlled energy storage. For example, octanitrocubane and heptanitrocubane have been studied as high-performance explosives. These compounds also typically have a very high density for hydrocarbon molecules.

What explosive has the highest re factor?

Octanitrocubane

Octanitrocubane has a detonation velocity of 10,100 m/s, making it the fastest known explosive. Its R.E. factor is 2.38, making it the most effective chemical explosive known.

What is the most explosive liquid on Earth?

Like all azides, it reacts with water to emit explosive, highly toxic hydrogen azide. Azidoazide azide has been called “the most dangerous explosive material in the world.” It is also No.

Why is TNT unstable?

TNT is explosive for two reasons: TNT is composed of the elements carbon, oxygen and nitrogen. When TNT explodes it forms several covalent gases: CO, CO2 and N2 that are very stable. The production of these very low energy (stable) bonds means that a great deal of energy is released.

What molecules make up dynamite?

Nitroglycerine is an explosive liquid which was first made by Ascanio Sobrero in 1846 by treating glycerol with a mixture of nitric and sulphuric acid.

Is cubane reactive?

The 90-degree bonding angle of the carbon atoms in cubane means that the bonds are highly strained. Therefore, cubane compounds are highly reactive, which in principle may make them useful as high-density, high-energyfuels and explosives (for example, octanitrocubane and heptanitrocubane).

Who discovered cubane?

Philip Eaton
The highly symmetrical C8H8 hydrocarbon cubane was first synthesized by Philip Eaton in 1964. Before that, many thought that it could not be synthesized because of the great strain generated by its 90° C–C–C bond angles.

What is in Semtex?

Semtex is based on PETN-RDX (Penaerythrite tetranitrate – Research Development Explosive), a plastic explosive formerly made by Explosia in the Czech Republic. It is a favourite explosive of terrorist groups, particularly PIRA, as only small amounts are needed for horrendous results.

What are the 3 types of explosives?

1. Introduction

• blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
• perforating explosives (intended for use in the oil and gas well industry);
• special-application explosives (high explosives used for other applications, including primary explosives).

What two chemicals will explode when mixed?

Peroxides (inorganic), when mixed with combustible materials, barium, sodium, and potassium, form explosives that ignite easily. Phosphorus (P), both red and white, forms explosive mixtures with oxidizing agents. White (also called yellow) P should be stored under water, in glass, because it is pyrophoric.

What is C4 made of?

C4 was used during the Vietnam War as part of demolition blocks; today, it is commonly used in both military and civilian settings for demolition and flares. C4 is composed of RDX (91%), dioctyl sebacate (5.3%), polyisobutylene (2.1%), and mineral/motor oil (1.6%) [1].

What is the double bond equivalent of cubane?

DBE=2(16+2)−8=5.

What is DBE of cubane?

$\Rightarrow DBE=5$ Therefore, the double bond equivalent of cubane is $5$.

What is the strongest plastic explosive?

It was concluded that PEX-1 has compatible ingredients, it has the highest detonation velocity of all the studied plastic explosives, and its sensitivity is in the same level of the studied plastic explosives except Semtex 1A.

Is C-4 edible?

When ingested, C4 results in serious CNS effects such as generalized seizures in addition to renal and GI symptoms. Based on previous reports, the toxic presentation is transient and treatment is supportive. Critical actions include airway maintenance, seizure control, and fluid resuscitation.

What are 2 types of high explosives?

High explosives will be referred to Type E explosives, and there will be three sub-types in this group:

• 1 – blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
• 2 – perforating explosives (intended for use in the oil and gas well industry);

What happens if you mix acetone and peroxide?

Hydrogen peroxide mixed with organic solvents is known to form dangerous peroxides. Hydrogen peroxide and acetone is an especially hazardous combination that can form various explosive peroxides when mixed at high concentration while using an acid catalyst.

What happens if you combine ammonia and bleach?

Mixing Bleach and Ammonia
When bleach is mixed with ammonia, toxic gases called chloramines are produced. Exposure to chloramine gases can cause the following symptoms: Coughing. Nausea.

Can C4 destroy a tank?

C4 is a great anti-tank weapon if a LAW is not available. If the C4 is attached to the tank when it detonates, it will immediately destroy the tank.

Is Semtex and C4 the same?

Semtex is a very powerful explosive device, similar to C4. It was developed in Czechoslovakia. Because of its similarities, it was nicknamed the “Terrorist’s C4” during the Cold War. The explosive is made with mainly RDX and PETN, in addition with numerous binders and stabilizers.

What is the Du of cubane?

Degree of unsaturation= 210=5. Was this answer helpful?

What is DBE value?

The DBE number can be calculated from the formula using the following equation: DBE = UN = PBoR = C – (H/2) + (N/2) +1, where: C = number of carbon atoms, H = number of hydrogen and halogen atoms, and N = number of nitrogen atoms. One DBE = one ring or one double bond.

How explosive is Semtex?

Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications.
…
Composition.

Is C4 the same as Semtex?

C-4 is a plastic explosive substance similar in structure to Semtex that is used by both military and terrorist organizations. It has a reputation for producing a buzz as well as a bang.
