molecules with a plane of symmetry between the chiral centers are achiral and meso. identify which of the following molecules ar
maks197457 [2]

Molecules with a plane of symmetry between the chiral centers are achiral and meso. From the given molecules (Picture attached) only (A) compound 1 is meso.

When compounds possess a plane of symmetry between the chiral centers they are called achiral or meso compounds. Among the given compounds (A) compound 1 have a plane of symmetry. So we can say compound one is a meso or achiral compound. Compounds two, three, and four have no plane of symmetry, as you can see in the structures attached. So all other compounds (compound 2, compound 3, and compound 4) except compound one are not meso or achiral.

You can also learn about meso compounds from the following question:

What is a result of the unequal electron sharing in a water molecule?
Katarina [22]

Answer:

The right choice is  c. Water molecules have a weakly positive hydrogen end.

Explanation:

The unequal sharing of electrons in water molecule gives a slight negative charge near its oxygen atom ( see image below) and a slight positive charge near its hydrogen atoms. A neutral molecule that has a partial positive charge at one end and a partial negative charge at the other, it is a polar molecule.

so

a. Water molecules have a nonpolar bond.

It is wrong choice because water has polar bond .

b. Water molecules have a weakly positive oxygen end.  

Also, a wrong choice due to water molecule gives a slight negative charge near its oxygen atom.

c. Water molecules have a weakly positive hydrogen end.  

This is the right choice.

d. Water molecules have two oxygen and two hydrogen atoms

It is wrong choice because water has one oxygen and two hydrogen atoms

<u>So, the right choice is</u>

c. Water molecules have a weakly positive hydrogen end.

Which of the following describe chemical properties
alexandr1967 [171]
Chemical properties are all those properties that are shown when the chemical is a part of a reaction or is changed in any way. Unlike physical properties, they affect the composition of the chemical and the way it behaves, while physical does not change the chemical itself. Such properties are toxicity, flammability, reaction with other elements, stability, and many more.

What is happening to the temperature of the substance BEFORE AND AFTER the phase changes?
Neporo4naja [7]
First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.
