<span>Answer:
             Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as <u>Chiral Molecules</u>.

Explanation:
                   Chiral molecules have stereogenic centers. When plane polarized light is fall on these compounds they rotate the light either in clockwise or anti clockwise direction. The mirror images of chiral moleculecules are non-superimposable.  Below few examples for molecules containing chiral centers are given.</span>

What is the name of the acid formed when h2s gas is dissolved in water?
Serjik [45]
The name of the acid that is formed when hydrogen sulfide is dissolved in water would be hydrosulfuric acid. It has the same chemical formula as hydrogen sulfide which is H2S. It is classified as a weak acid which partially ionizes into hydrogen sulfide ions and hydronium ions. It is a very toxic substance and is distinguished by its strong odor which is compared to an egg that is rotting. It can be found in high concentrations in the crust of the Earth, in volcanic emissions and in many fossil fuels. To produce this acid, the gas hydrogen sulfide is dissolved into the water. However, this acid is not produced since it does not have any industrial application.

What is the iodine test?
wariber [46]
is used to test for the presence of starch. Starch turns into an intense "blue-black" colour upon addition of aqueous solutions of the triiodide anion, due to the formation of an intermolecular charge-transfer complex. In the absence of starch, the brown color of the aqueous solution remains.
