<h3>Answer:</h3>

Saturated: i) 3-Methyloctane ii) Heptane iii) Propane

Unsaturated: i) Heptyne ii) Cyclopentene

<h3>Explanation:</h3>

Saturated Hydrocarbons are those organic compounds which are saturated <em>i.e. </em>all the bonds between carbon atoms are single. In other words the bonds between carbon atoms are sigma bonds (formed due to head to head overlap of orbitals)

Examples of Saturated Hydrocarbons are highlighted in Red color in attached figure.

Unsaturated Hydrocarbons are those organic compounds which are unsaturated <em>i.e. </em>they contain either one or more than one double or triple bonds along with or without single bonds.. In other words one or more bonds between carbon atoms are pi bonds (formed due to side wise overlap of p orbitals)

Examples of unsaturated Hydrocarbons are highlighted in Blue color in attached figure.

To draw a Lewis structure for a

liq [111]

40 electrons

Explanation:

The N for silicon tetrachloride, SiCl₄ is 40 electrons. The needed electrons that would be used to complete the lewis structure of the compound is actually 40 electrons. This number of electron will help the compound attain a noble configuration.

The compound SiCl₄ is a covalent one. Here, there is sharing of electrons between two atoms.
In drawing the electron dot formula, one must take into account the Available electrons and the Needed electrons.
The Available electrons are sum of the valence electrons that can be accessed for the bonding. Si has 4 valence electrons, Cl has 7 valence electrons this makes a total of 4 + 7(4 atoms of chlorine), 32 available electrons.
But to make a complete octet like that of noble gases, each atom most have 8 complete outer most electrons. This is the needed number of electrons. Since there are 5 atoms i.e 4 atoms of chlorine and 1 atom of Silicon, the needed electrons will be 5x8 = 40 electrons.

PLEASE HELP I NEED IT!!!!!

galina1969 [7]

Answer:
Molarity = 2.3 M

Explanation:
Molarity can be calculated using the following rule:
Molarity = number of moles of solute / volume of solution

1- getting the number of moles:
We are given that:
mass of solute = 105.96 grams
From the periodic table:
atomic mass of carbon = 12 grams
atomic mass of hydrogen = 1 gram
atomic mass of oxygen = 16 grams
Therefore:
molar mass of C2H6O = 2(12) + 6(1) + 16 = 46 grams
Now, we can get the number of moles as follows:
number of moles = mass / molar mass = 105.96 / 46 = 2.3 moles

2- The volume of solution is given = 1 liter

3- getting the molarity:
molarity = number of moles of solute / volume of solution
molarity = 2.3 / 1
molarity = 2.3 M

Hope this helps :)
