What is C₆HCl₅O?

C₆HCl₅O Is a chemical compound known as Pentachlorophenol or PCP and is used as a disinfectant. The molecule is made up of Chlorine, Hydrogen, Oxygen and Carbon. Below are diagrams showing what the molecule looks like in 3d, Lewis Structure and the Dash Structure. Also it shows its polarity, covalent bonds and forces of attraction.

Covalent Bonds in C₆HCl₅O : 

• When you find the difference between the two molecules if it is between 0-1.7 it is covalent. If it is from 1.7- it is ionic. The closer to 0 the bond becomes more covalent anything above 1.7 makes the bond ionic.

This demonstrates the bond between chlorine and Carbon. The difference between the two is .9 making it moderately covalent

This demonstrates the bond between Oxygen and hydrogen. The difference is 1.3 making it somewhat covalent.

This demonstrates the bond between Oxygen and Chlorine. The difference was .3 making it very covalent.

Polarity
Polarity refers to a separation of Electric charge between two molecules . In this molecule Chlorine and Oxygen both have negative charges. Hydrogen however has a positive charge. Therefore because not al of the charges in the molecule are the same C₆HCl₅O is polar.

Intermolecular Forces

In a sitchuation where two molecules of C₆HCl₅O ( PCP) became attracted to each other what Intermolecular forces would be diplayed? 

The arrows point the dots which represent dipole-dipole and the line that represents hydrogen bonding.

In this molecule the Intermolecular forces represented are London Dispersion, Dipole-Dipole and Hydrogen bonding. 

• London Dispersion is found at all molecule attractions. Dispersion forces occur because a temporary pole is formed through motion and an uneven amount of electrons distributed. 

• Dipole - Dipole forces occur because a positive end of one polar molecule and the negative end of another polar molecule attract. ( this is demonstrated though the dots between O and H . O is negative and H is positive.)

• Hydrogen bonding is a type of hydrogen bonding. Here it is the bond between the hydrogen atom and the oxygen atom. ( In other cases it can also be between N or F. It is represented as a straight line. )
