Answer:

8 valence electrons

Explanation:

We are given the atom has 10 electrons.

The first electron shell holds 2 electrons (maximum)

The second electron shell holds 8 electrons (maximum)

2+8=10

Therefore we would have 2 electrons in the first shell and 8 in the second.

Valence electrons are the outermost electron, and since the second shell is the outermost for the atom, it has 8 valence electrons.

Write the name of this structure ​
faltersainse [42]

Answer:

The name of the compound is:

4–bromo–5,5–dichloro–hex–3–ene–1–yne

Explanation:

To the above compound, we simply do the following:

1. Identify the functional group of the compound.

2. Locate the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent group attached.

4. Give the substituents the lowest possible count alphabetically.

5. Combine the above to obtain the name of the compound.

Now, we shall determine the name of the compound as follow:

1. The compound has carbon to carbon triple bond (C≡C) yne and carbon to carbon double bond (C=C) ene.

2. The longest continuous carbon chain is 6 i.e hexane.

3. The substituents group attached are:

i. Bromine (bromo), Br

ii. Chlorine (Chloro), Cl

4. In counting, ene comes before yne. But in this case, ene assumes same position from either side, So we shall consider counting from the side that gives yne the lowest count. Thus, ene is at carbon 3 and yne is at carbon 1. Therefore,

i. Bromo, Br is at carbon 4.

ii. Chloro, Cl appears twice and both are at carbon 5.

5. The name of the compound is:

4–bromo–5,5–dichloro–hex–3–ene–1–yne.
