Draw the structure of the bromohydrin formed when (Z)-3-hexene reacts with Br2/H2O. Use the wedge/hash bond tools to indicate st
Ipatiy [6.2K]

Answer:

(3R,4R)-4-bromohexan-3-ol

Explanation:

In this case, we have  reaction called <u>halohydrin formation</u>. This is a <u>markovnikov reaction</u> with <u>anti configuration</u>. Therefore the halogen in this case "Br" and the "OH" must have <u>different configurations</u>. Additionally, in this molecule both carbons have the <u>same substitution</u>, so the "OH" can go in any carbon.

Finally, in the product we will have <u>chiral carbons</u>, so we have to find the absolute configuration for each carbon. On carbon 3 we will have an "R" configuration on carbon 4 we will have also an "R" configuration. (See figure 1)

I hope it helps!

Use the information below to explain why the atomic radius decreases down a group.
notsponge [240]

Answer:

Detail is given below

Explanation:

Atomic radii trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

In A we can see that there is one positive charge and force of attraction is 2.30×10⁻⁸ N and distance is 0.10 nm

In B we can see that negative charge is further away from nucleus because of greater distance thus force of attraction will be less. 0.58×10⁻⁸ N

In C this distance further increases and force also goes in decreasing 0.26×10⁻⁸ N.

The volume of a carbon atom is 1.9 x 10–30 m3. What is the radius of the atom in picometers? The volume of a sphere is (4/3)(pi)
skelet666 [1.2K]

Volume of sphere = \frac{4}{3}\pi r^{3}

where, \pi = 3.14

r = radius of sphere

Put the given value of volume in above formula i.e. (1.9\times 10^{-30}m^{3})

Thus,

1.9\times 10^{-30}m^{3} = \frac{4}{3}\3.14 r^{3}

1.9\times 10^{-30}m^{3} = 4.1867 r^{3}

r^{3} = \frac{1.9\times 10^{-30}m^{3}}{4.1867}

r^{3} = 0.453\times 10^{-30}m^{3}

r = \sqrt[3]{0.453\times 10^{-30}m^{3}}

= 0.768\times 10^{-10}m

=  7.68\times 10^{-12}m

=  7.68 picometers

Thus, radius of the carbon atom is 7.68 picometers
