Identify the chirality center (sometimes called chiral atom) or centers in each compound. if the molecule does not contain a chi
rality center, do not highlight any of its atoms. select an atom by clicking on it. selected atoms will be highlighted green.
1 answer:
Chiral Carbons are those carbons which are attached to four different atoms or groups. Below are the four structure, Among these structures,
Structure C has no chiral carbon because the carbon to which methyl group and hydrogen atom attached is further attached to groups of same environment.
Structure A has one chiral center (highlighted RED).
Structure B has three chiral centers.
Structure D has two chiral centers.

Solution:- We are asked to calculate the molarity of sodium carbonate solution as well as the sodium and carbonate ions.
Molarity is moles of solute per liter of solution. We have been given with 6.73 grams of sodium carbonate and the volume of solution is 250.mL. Grams are converted to moles and mL are converted to L and finally the moles are divided by liters to get the molarity of sodium carbonate.
Molar mass of sodium carbonate is 105.99 gram per mol. The calculations for the molarity of sodium carbonate are shown below:
=
So, molarity of sodium carbonate solution is 0.254 M.
sodium carbonate dissociate to give the ions as:
There is 1:2 mol ratio between sodium carbonate and sodium ion. So, the molarity of sodium ion will be two times of sodium carbonate molarity.
= 0.508 M
There is 1:1 mol ratio between sodium carbonate and carbonate ion. So, the molarity of carbonate ion will be equal to the molarity of sodium carbonate.
