Simple Alkanes, Alcohols, and Ethers

 

I just noticed how easy it is to represent the different alkanes, alcohols, and ethers using a standard keyboard, so as to show how little difference there really is in the alkane solvents, the alcohols, and the ethers.

 

As you will note, all that it takes to make either an alcohol or an ether from an alkane, is one oxygen atom and the difference between an alcohol and an ether, is where it is placed.

 

Note also that while butane is the basis for Diethyl Ether, because the butane molecule is split in the middle, it becomes two ethane molecules, separated by the oxygen molecule, hence the Di (2) Ethyl, instead of Butyl Ether.

 

An isomer, of course is the same molecules arranged differently, so Propanol and Isopropyl alcohol have the chemical same formula, as does Butyl alcohol, and Diethyl ether.

 

All of the alkanes, alcohols, and ethers starting with H5C12, or Pentane, use the Greek alphabet, but the lower alkane designation predate that naming system, so I use the pneumonic Mary Eats Peanut Butter, to keep track of the order of the first four alkanes and their derivatives.

 

 

 

Mary:

 

--H

HCH = Methane = CH4

--H

 

--H

HCOH = Methanol =CH4O

--H

 

Eats:

 

--HH

HCCH = Ethane = C2H6

--HH

 

--HH

HCCOH = Ethanol =C2H6O

-HH

 

Peanut:

 

--HHH

HCCCH = Propane = C3H8

--HHH

 

--HHH

HCCCOH = Propanol = C3H8O

--HHH

 

--HHH

HCCCH = Isopropyl Alcohol =C3H8O (isomer of propanol)

--HOH

----H

 

Butter:

 

--HHHH

HCCCCH = Butane = C4H10

--HHHH

 

--HHHH

HCCCCOH = Butyl Alcohol= C4H10O

--HHHH

 

 

--HH=HH

HCCOCCH = Diethyl ether = C4H10O

--HH=HH

very close, kirk.

 

the interesting picture is how chemically similar they are, when one contemplates the physical characteristics (aromatic) of say ether, methane, ethanol, isoprpyl, etc. the aromas are varied in many ways, including effect on humans. yet, they are so similar.
