Draw structures from the following names, and determine which compounds are optically active:(c) 1,2-dibromo-2-methylbutane

dolphi86 [110]

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) .

Which of the following statements regarding enzymes is FALSE? a. Enzymes alter the free energy change (ΔG) of the reactions whic

const2013 [10]

Answer:

Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

Explanation:

Enzyme are biological catalysts.

So they do alter the path of the reaction where the free energy change (or activation energy) is low then the non enzymatic pathway.

Thus the statement

Enzymes alter the free energy change (ΔG) of the reactions which they catalyze : True

It is known that for enzyme we function they need an optimum temperature and pH condition so the statement

Enzyme function is dependent on the pH and temperature of the reaction environment: true

This is also true that

Enzyme activity can be inhibited if the enzyme is bound by a noncompetitive inhibitor.

The false statement is : Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

In order to separate the components of a binary mixture, the relative volatility should be a) less than unity b) equal to unity

Tresset [83]

Answer: Option (c) is the correct answer.

Explanation:

A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.

And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.

For a binary solution the expression for relative volatility is as follows.

$\alpha = \frac{\frac{y_{i}}{x_{i}}}{\frac{y_{j}}{x_{j}}}$ = $K_{i}/K_{j}$

where, $\alpha$ = relative volatility of more volatile component i

$y_{i}$ = vapor-liquid equilibrium concentration of component i in the vapor phase

$x_{i}$ = vapor-liquid equilibrium concentration of component i in the liquid phase

$y_{j}$ = vapor-liquid equilibrium concentration of component j in the vapor phase

$x_{j}$ = vapor-liquid equilibrium concentration of component j in the liquid phase

So, when $\alpha$ > 1 then separation by distillation is easier in nature.

Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.
