It is the 2nd one
What does it mean when say that a 200-ml sample and a 400-ml sample of a solution of salt have the same
1 answer:
Answer:
<em>Read explanation.</em>
Explanation:
Molarity is a unit used to measure the ratio per unit volume of the solution. So, in other words, and in our case, we call it the
ratio.
So, the amount of solute (moles of salt) per ml of solution will be the same, but the number of moles in each solution will be obviously different.

The given compound 1,2-dibromo-2-methylbutane is an optically active compound .
Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .
It has chiral center.
Here , the chiral carbon is attached to the 4 distinct groups such as : methyl , ethyl , bromine , bromomethane .
<h3>What is di-symmetry?</h3>Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .
<h3>Chiral center :</h3>Have Sp3 hybridized center (4sigma bond ) .
4 distinct group is attached to the chiral atom. form non -superimposable mirror image .
<h3>What is optical isomerism ?</h3>Same molecular formula and same structural formula . also have same physical and chemical properties .
They differ in their behavior towards plane polarized light (ppl) .
