chemical equation for 1-pentanol?

Question

does anyone know the balanced chemical equation for the combustion of 1-pentanol please?!

Answer 1

If you are to succeed in organic chem, you must learn to balance chem equations...essentially this is a matter of intelligent trial and error to get the same number of each element's atoms on each side. Let me work you through the steps to balance this one:

The complete combustion of any hydrocarbon with oxygen results in production of only carbon dioxide and water...write out this 'skeleton'...
CH3CH2CH2CH2CH2OH is C5H12O
C5H12O + O2 ===> CO2 + H2O....not complete

The 5 C's must give 5 CO2's and 12 H's give 6 H2O's
C5H12O + O2 ===> 5CO2 + 6H2O....not complete

The O's on right total 16, so you need 8 O2's on left...BUT you already have one O in the alcohol...so you need 7.5 O2's on left
C5H12O + 7.5O2 ===> 5CO2 + 6H2O....not complete

Now the elements are equal on both sides...BUT you are not allowed to use half a compound...so multiply all by two
2C5H12O + 15O2 ===> 10CO2 + 12H2O...BALANCED

Did you follow these steps? This becomes easier with experience...you get a 'feel' for it....and plenty of practice helps too :-))

Answer 2

Principle: atoms in = atoms out

1-Pentanol is CH3CH2CH2CH2CH2OH, molecular formula C5H12O

So you need to complete the equation

C5H12O + xO2 = yCO2 + zH2O

Each carbon in C5H12O ends up as CO2; this tells you x

Each two hydrogens in C5H12O end up as H2O. This tells you y

Add up the number of oxygen atoms needed, divide by two, and that tells you z.

Sometimes in problems of this kind you end up with a fraction for one of the reagents. If that happens, just multiply through to get rid of it.

2 C5H11OH(g) + 15 O2(g) ---> 10 CO2(g) + 12 H2O(g)

I hope this helps you.
