Graphite is thermodynamically the most stable form of carbon.

Which allotrope of carbon is more thermodynamically stable?

All carbon allotropes are solids under normal conditions, with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen.

Why graphite is thermodynamically the most stable form of carbon?

At standard temperature and pressure conditions, graphite is the most thermodynamically stable form of carbon. This is because they are chemically inert or resistant and require high temperature to react with oxygen.

Which is thermodynamically least stable allotrope of carbon?

Graphite is the least stable form of carbon.

Which compound is the most thermodynamically stable?

Black phosphorus is the most thermodynamically stable allotropic form of phosphorus. It is stable at room temperature and pressure.

Which carbon atom is most stable?

Note: A tertiary carbocation forms the most quickly because it is the most stable.

Which states form of a molecule is thermodynamically more stable?

Chemical systems might undergo changes in the phase of matter or a set of chemical reactions. State A is said to be more thermodynamically stable than state B if the Gibbs free energy of the change from A to B is positive.

Which is thermodynamically most stable?

Graphite is thermodynamically the most stable form of carbon.

Which allotrope is more stable?

Graphite is considered as the most thermodynamically stable material.

Which is the most stable carbocation among the following?

The most stable carbocation is t-alkyl carbocation because the order of stability of alkyl carbocation is t-alkyl >s-alkyl> p-alkyl *> CH3 carbocation.

Which is more stable graphite or diamond?

Even with accounting for the flexural modes, graphite is still more stable than diamond at 0 K, but the difference in Gibbs energies is even smaller (1.39–1.55 kJ mol1) than at room temperature.

Which is the purest form of carbon?

Diamond is the purest form of carbon. Different forms of the same chemical substance are called allotropes. Graphite and diamond are two major allotropes of carbon. Diamond is a form of carbon in which each carbon atom is covalently bonded to four other carbon atoms.

Which Carbanion is more stable?

Note: Remember primary carbanion and methyl carbanion are the most stable carbanions. If electron-withdrawing groups are present in the molecule then, carbanion stability increases due to more stabilization of negative charge in the molecule.

Is diamond thermodynamically stable?

At normal temperatures and pressures, graphite is only a few eV more stable than diamond, and the fact that diamond exists at all is due to the very large activation barrier for conversion between the two. ... So diamond is said to be metastable, since it is kinetically stable, not thermodynamically stable.

Which is more stable alpha graphite or beta graphite?

The two known forms of graphite, alpha (hexagonal) and beta (rhombohedral), have very similar physical properties, except that the graphene layers stack differently: stacking in alpha graphite is ABA, as opposed to ABC stacking in energetically less stable and less common beta graphite.

Which is the most stable allotrope of Sulphur?

Rhombic sulphur is the most stable allotropic form of sulphur.

Which allotrope of Sulphur is thermodynamically stable at room temperature?

The rhombic allotrope of sulphur (α-suphur) is thermally stable at room temperature.

Which free radical is the most stable?

Allyl radical is in turn less stable than benzyl free radical. Therefore, the most stable free radical is benzyl free radical. Hence the correct option is (B).

Which is more stable alpha or beta Sulphur?

Answer: Below 369 K alpha sulphur is stable and above this it transforms into beta sulphur. At 369K both the forms are stable.

What is thermodynamically stable product?

The thermodynamic product is the most stable product with the lowest energy (the relative stability of the products) The distinction is relevant when product A forms faster than product B because the activation energy for product A is lower than that for product B, yet product B is more stable.

What is thermodynamically unstable?

A system is called thermodynamically unstable when there exists a state where the system will have lower energy than it currently has. A dispersion can be thermodynamically unstable, but can still be kinetically stable.

What is thermodynamic and kinetic stability?

Thermodynamic and kinetic stability are two important chemical terms describing systems with chemical reactions. Thermodynamic stability is the stability of the lowest energy state of a system while kinetic stability is the stability of the highest energy state of a system.

Which of the following are thermodynamically stable?

Thus, graphite is thermodynamically stable.

Why are thermodynamic products more stable?

Thermodynamic products contain an internal double bond and the reaction is reversible. Also, when reactions are carried out, thermodynamic products are more stable than kinetic products because they are more substituted.

What is a thermodynamically stable reaction?

A thermodynamically stable reaction is one that basically does not react. As a result, it is independent of the pathway between reactants and products.
