Answer:
The last figure (with the name 3-Chloro-2-iodo-4-methylhexane) is correct.
Explanation:
---> It gives the correct numbering of the positions of each Iodine Chlorine and Methyl which are attached at 2, 3 and 4 respectively
---> and also the names are given on alphabetical order (i.e. first Chlorine then Iodine and then Methyl)
Element, mixture, heterogeneous, Viscosity, compound
I suppose that the question ask the following:
What is the mass of a sample, composed of C₃H₅N₃O₉ molecule, that contains 100 g carbon?
First we calculate the molecular mass of our molecule C₃H₅N₃O₉.
molecular mass = 12 × 3 + 1 × 5 + 14 × 3 + 16 × 9 = 227 g/mol
Now we devise the following reasoning:
if 227 g of our molecule contains 27 g of carbon
then X g of our molecule contains 100 g carbon
X = (100 × 227) / 27 = 840.7 g
The information given shows that the intermolecular force in C will be higher than the intermolecular force in D.
<h3>What is a intermolecular force?</h3>
It should be noted that an intermolecular force simply means the attractive or repulsive force which arise between the molecules of a substance.
In this case, the intermolecular force in D will be higher than the intermolecular force in C.
This is attributed to the fact that the dominant intermolecular force in C is hydrogen bonding while in D, it's dipole - dipole bonding.
It should be noted that hydrogen bonding is the highest intermolecular force in gases and liquids.
In D, due to the dipole-dipole force, the ions that has same charge will repel each other.
