Which allotrope of phosphorus is kinetically most stable?
Black phosphorus
Black phosphorus is the most thermodynamically stable allotropic form of phosphorus.
Which of the phosphorus is most stable?
Black phosphorus is thermodynamically the most stable form at room temperature and pressure; the atoms are linked together in puckered sheets, like graphite.
Which allotrope of phosphorus is highly unstable?
Which allotrope of phosphorus is poisonous? The least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes is white phosphorus. It eventually changes to red phosphorus, a light and heat-accelerated transition.
Which form of black phosphorus is most stable?
Being most stable, black phosphorus is less reactive in nature. Thus, the most thermodynamically stable allotropic form of phosphorus is black. Thus, the correct option is (C) black.
Which of the following allotropic forms of phosphorus is the most stable least reactive has a graphite like structure and is a good conductor of electricity?
Black phosphorus is the most stable allotrope of phosphorus. It has a layered structure.
Which of the following allotropic forms of phosphorus is the most stable least reactive and has a graphite like structure?
Black phosphorus is the thermodynamically stable form of phosphorus at room temperature and pressure.
Which is the most stable allotrope of carbon?
Graphite
The correct answer is Graphite. Change in enthalpy of carbon in diamond to graphite form is negative. It shows that graphite should be more stable than diamond. The melting point of graphite is more than diamond which implies that it is a thermodynamically most stable allotrope of carbon.
Why red phosphorus is stable?
Red Phosphorus has more atoms linked together in a network than white phosphorus does, which makes it much more stable. It is not quite as flammable, but given enough energy it still reacts with air. For this reason, we now use red phosphorus in matches.
Is red phosphorus stable?
Phosphorus, a nonmetallic element of the group 15 in the periodic table, has three main allotropes: white, red, and black phosphorus. Red phosphorus is a relatively stable allotrope of phosphorus, and both amorphous and crystalline phases are known to be present.
Which is more stable alpha or beta black phosphorus?
Alpha Black phosphorus is more stable than beta one. Alpha consists of opaque monoclinic OR rhombohedral crystals, while beta having corrugated sheets that form flaky layered crystals. Black phosphorus is most stable then all other allotropes of Phosphorus. It melts at 860K.
Why red phosphorus is more stable than white phosphorus?
Red phosphorous is polymeric in structure. There is one additional bond formed in phosphorous tetrahedron resulting in chain structure. White P is the least stable,the most reactive,the most volatile and gradually changes to red P.
Which allotrope of phosphorus is the most stable A white phosphorus B red phosphorus black phosphorus and phosphine?
Black phosphorus is the most stable allotrope of phosphorus. It has a layered structure.
Which is the most stable allotrope of phosphorus?
Black phosphorus is the most stable allotrope of phosphorus. It has a layered structure. It is a very highly polymerised form of the element. We can find black phosphorus in two main forms. They are alpha black phosphorus and beta black phosphorus.
Why is the thermodynamically most stable allotrope also the kinetically most stable?
From this it can easily be seen, that the thermodynamically most stable allotrope is also the kinetically most stable allotrope. This is due to the fact, that the barriers for interconversion of the different allotropes always have to be higher for the most stable one.
Is black phosphorus the thermodynamically and kinetically most stable form of phosphorus?
If this was not true, then 2 cannot be the global minimum and hence not the thermodynamically most stable modification. Having established that, it is therefore true, that black phosphorus is the thermodynamically and kinetically most stable form, see Hollemann-Wiberg, p. 680.
Which phosphorus is the most reactive?
The least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes is white phosphorus. It eventually changes to red phosphorus, a light and heat-accelerated transition. Why is phosphorus called the devil’s element?
