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) .

A gas has a volume of 4 liters at 50 oC. What will its volume be (in liters) at 100oC
san4es73 [151]

Answer:

The volume of the gas at 100°C is 4.6189 liters.

Explanation:

For this problem we are going to use Charles' law. Charles' law states that the volume is directly proportional to temperature given that the pressure is constant. In order to use the equation, the unit of temperature should be in Kelvin.

The working equation is:

=

where V1 and T1 are the initial volume and temperature while V2 and T2 are the final conditions.

Let us convert first the temperatures before solving for the final volume.

To convert Celsius to Kelvin just add 273.15 to temperature in Celsius.

50°C + 273.15 = 323.15 K

100°C + 273.15 = 373.15 K

Solving for the final volume:

V₂ =

V₂ =

V₂ = 4.6189 L

Therefore the final volume of the gas at 100°C is 4.6189 L.

In humans, glucose may be the product of chemical digestion when what kinds of foods are eaten? A) carbohydrates like bread B) f
forsale [732]
<h3>Answer:</h3>

Carbohydrates like bread

<h3>Explanation:</h3>
  • Chemical digestion involves the breakdown of food molecules by the use of enzymes to generate simpler molecules that can be absorbed into the body's metabolism.
  • During chemical digestion, carbohydrates are broken down into simple molecules such as glucose which can be easily absorbed in the small intestines.
  • Monosaccharides such as glucose are the building blocks of carbohydrates and can be easily absorbed by the body through the small intestines.
  • Proteins are broken down into amino acids while lipids are broken down into fatty acid and glycerol during chemical digestion.
