Four different substituents are required on a carbon atom for it to be chiral.
<h3>What is Chiral Carbons ?</h3>
The carbon atom which is attached with four different types of group of atoms or atoms is called Chiral carbon. Chiral molecules are non superimposable on their mirror images. Chiral carbon is also called asymmetric carbon.
Example:
In the above example we can see that carbon atom has 4 different group attached with it that is Br, Cl, H, CH₃.
Thus from the above conclusion we can say that Four different substituents are required on a carbon atom for it to be chiral.

<h3>What is spectrometric method?</h3>
- A technique called spectrophotometry uses light intensity measurements as a beam of light travels through a sample solution to determine how much a chemical compound absorbs light.
- Every chemical either absorbs or transmits light across a specific spectrum of wavelengths, according to the fundamental principle.
- There are two main techniques used among the various forms of spectrophotometry:
- ultraviolet-visible range spectrophotometry, which examines the reflectance of certain spectra,
- and absorption spectrophotometry, which examines the absorption of radiation and particular spectra of light.
- Applications of spectrophotometry are useful for determining how well gases, liquids, and solids transmit, reflect, and absorb light.

Ions can be atomic or molecular. If an atom contains either positive or negative charge it said to be atomic cation or atomic anion.
When a molecule carry positive or negative charge it is called as polyatomic cation or polyatomic anion. Generally charged or ionized molecules are called as polyatomic ions.
In given question Fe(HCO₃)₃ ionizes as follow,
Fe(HCO₃)₃ → Fe³⁺ + 3 HCO₃⁻
The Ions produced are Fe³⁺ and HCO₃⁻. Fe³⁺ is said to be atomic (Ferric) ion and HCO₃⁻ (Bicarbonate) is polyatomic ion or molecular ion.
Answer:
The dissociation constant for hydrochloric acid is greater than the dissociation constant for acetic acid.
Explanation:
yes.
