When placed in a 100-mL square box, a substance has a spherical shape and has a volume of 50 mL. When placed in a 100-mL circula

ikadub [295]

Solution: There are major three phases of substance, namely solid, liquid and gas.

Here, solid substances have definite shape, they are rigid and can not change their volume or shape if kept in any container.

Liquid substances do not have any shape of their own, they take shape of the container in which they are kept. They are compressible in nature.

Gaseous substances also do not have their own shape, the molecules of gas continuously move in the container in which they are stored. Gases are highly compressible in nature.

Here, a substance when placed in a 100-mL square box have spherical shape and 50 mL volume. The shape and volume of the substance do not change when it is placed in a 100-mL circular tube, that means it does not change the shape with change of container and the state of substance will be solid.

Draw structures from the following names, and determine which compounds are optically active:(b) 3-chloro-2,2,5-trimethylhexane

inn [45]

The given compound 3-chloro-2,2,5-trimethylhexane 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 has 4 distinct groups such as : chlorine , hydrogen , 2-methylpropyl , tertbutyl .

<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) .
