What do you mean by chirality axis?
In science, pivotal chirality is an exceptional instance of chirality wherein a particle contains two sets of synthetic gatherings in a non-planar plan about a hub of chirality so the particle isn't superposable on its mirror image. The hub of chirality (or chiral hub) not set in stone by a compound bond that is compelled against free revolution either by steric obstruction of the gatherings, as in subbed biaryl mixtures like BINAP, or by torsional firmness of the bonds, as in the C=C twofold bonds in allenes, for example, glutinic corrosive. Pivotal chirality is most generally seen in subbed biaryl compounds wherein the turn about the aryl bond is limited so it results in chiral atropisomers, as in different ortho-subbed biphenyls, and in binaphthyls like BINAP.
Pivotal chirality contrasts from focal chirality (point chirality) in that hub chirality doesn't need a chiral focus like an uneven carbon particle, the most widely recognized type of chirality in natural mixtures. Attaching to hilter kilter carbon has the structure Cabcd where a, b, c, and d should be unmistakable gatherings. Allenes have the structure abC=C=Ccd and the gatherings need not all be particular insofar as gatherings in each pair are unmistakable: abC=C=Cab is adequate for the compound to be chiral, as in penta-2,3-dienedioic corrosive. Essentially, chiral atropisomers of the structure abC−Ccd might have a few indistinguishable gatherings (abC−Cab), as in BINAP.

What is Molarity?Molarity is defined as the ratio of moles of solute to the volume of solution.
Mathematically,
Molarity = moles of solute / volume of solution
Step 1 : Calculation of molesGiven,
Initial volume of CuSO4 = 4 ml = 4/1000 = 0.004 l
Molarity of CuSO4 = 0.0250 m

Explanation:
The dilithium molecule is shown in the final diagram (Li2). The bonding orbital is filled by the 2s electrons rather than the 1s electrons, who are not involved in the bonding. Li2 has a bond order of 1 and is a molecule that is stable in the gas phase.
The number of chemical bonds that exist between two atoms is known as bond order.
Dilithium (Li2)
Bond Number = 2
Bonding electrons = 0 and anti-bonding electrons = 1
The p electrons entirely occupy the bonding orbital without the 1s electrons participating in bonding, leaving the antibonding orbital empty and resulting in a bond order of 1, suggesting a stable molecule (in this case, in the gas phase).
Lithium possesses 3 electrons in its neutral state because of its atomic number. Li2 will also have six electrons. However, the chemical formula we are given (Li2) has a negative charge, hence this compound also contains an additional electron (RED). Consequently, there are 7 electrons in all.

A sample of an ideal gas at 12.4 atm and 15.0 l is allowed to expand against a constant pressure 3.00 atm at a constant temperature. -13.2kJ is the work done (in kj) by the expanding gas.
What is Constant temperature ?Since the heat energy created during a state change is used up by altering the state of matter as well as by breaking many bonds or attractive forces, the temperature of any substance stays constant during the process.
Isothermal processes are defined as those that occur at constant temperature. There are many isothermal processes that are used often. At constant temperatures, the working fluid undergoes a change in phase during the boiling and condensing processes.
That's right; using Boyle's Law to determine V2 requires P2, which is based on the constant external pressure of 2.00 atm.
But after that, you must look for a job. w= P(ΔV)
Constant pressure = 3.00 atm
Since the gas is releasing energy, our pressure is negative in this situation.
Consequently, w= -2.00atm*(65L)= -130Latm
But because the inquiry requests working in kJ, it must first be transformed to J before kJ.
-13.169J/1000J/kJ = -130L/atm (101.3J/L/atm)

Give a structural formula for the carbocation intermediate that leads to the major product in the reaction of hydrogen chloride with cis−2−butene.
The major product formed when hydrogen chloride reacts with 2−methyl−2−butene proceeds through a tertiary carbo cation intermediate.
An addition reaction occurs when 2 methyl 2 butene and hydrogen chloride are combined. The Markovnickov rule states that the carbon atom with the fewest hydrogen atoms receives the negative part of the addition. As a result, carbon 2 will be increased by the addendum's negative portion.
The carbocation will be carbon-2 as indicated in the figure that is linked to this answer since this reaction proceeds through an ionic mechanism. This carbon atom is the one to which chlorine will finally bond.
A chemical compound known as hydrogen chloride (HCl) contains a polar covalent bond between chlorine and hydrogen atoms.
