<h3>What is Boyle's Law?</h3>It is a gas law that states the pressure decrease with the increase in the pressure.
By the formula
Given that, volume1 is 2.3l
Pressure1 is 4 atm.
Pressure2 to 0.65 atm.
V2 is to find?
Putting the values in the equation
Thus, the new volume of the bottle is 5.07 L.

Explanation:
<u>Ligands:</u> In co-ordination chemistry ligands are ion, molecule or any species which donates electron pair to central metal atom.
Depending on the type of interaction Ligands are of three types.
- Sigma donor only
- sigma as well as pi donor
- pi acceptor ligand
let's understand each type of Ligands individually & in more detail.
1 - Sigma donor only: This is a unidirectional interaction, in which filled ligand overlaps (head to head) with central metal atom/ion & donates pair of electron in the LUMO of metal.
generally all the molecules of 2nd period without pi bond comes in this category, below are few example of sigma donor ligands,
2- Pi donor: This in also a unidirectional interaction between ligand & central metal atom but the along with head to head overlap, side overlapping takes place.
generally protonated neutral molecules who have more than one pair to donate show such interaction, for e.g.
NH3 have two lone pair to donate but the energy level of both the lone pairs are different hence when it is neutral it only donates one pair of electron. but when NH3 is protonated to NH2- it have two electron pairs (negative charge+ lone pair) to donate & both the pairs have same energy level. example of such ligands are below,
3- Pi acceptor ligand: This is a bidirectional interaction between ligand & central metal atom/ion, the filled orbital of ligand undergoes head to head to overlap with vacant orbital of central metal atom, & filled D orbital of central metal donates their pair to vacant LUMO of ligand.
depending on the LUMO pi acceptor ligands are further classified into two categories.
