Yes, but “1,2-dimethylpropanol” is not the correct name for this compound. In fact, this compound has a carbon chain of length 4 that contains the principal functional group. Its correct name is 3-methylbutan-2-ol.

Propanol has two isomers, propan-1-ol and propan-2-ol. When any of the isomers is boiled with Al₂O₃,dehydration takes place to give propylene. Order of reactivity of alcohols for dehydration is 3⁰ 〉 2⁰ 〉1⁰

Many of the reactions in the early stages of the reforming process actually remove hydrogen from the feedstock. (Those are all endothermic reactions, which is why you see a temperature drop in the early reactors.)
In the last reactor, hydrocracking takes place to remove low-octane components that weren’t already converted in the earlier stages. This is a hydrogenation reaction and creates a temperature rise across the reactor. It also consumes some of the hydrogen that was produced in the early reactors.

Propene reacts with hydrogen bromide to form propyl bromide. Propyl bromide reacts with aqueous solution of sodium hydroxide forms propyl alcohol.Propyl alcohol is oxidized with potassium dichromate in presence of sulfuric acid forms propanal. Finally,propanal is oxidized with potassium dichromate in presence of sulfuric acid forms propanol.

When naming an organic compound as in aliphatic hydrocarbon, select the longest chain of carbon first.
Secondly see what it has an active group, such as carboxylic acid, amine or alcohol. Name it. Then look for any side chain.
The correct name for this particular compound is 2-Methyl-1-butanol.

Oxidation is the key! And if you don’T want to use your built-in “Nose-IR-ESR-detector”, you can use litmus-stripes.
1-propanol will be oxidized to propanonic acid which has a weird “acidic” sour smell almost like vinegar and will change pH of water.
C3H7OH → ox→ C2H5COOH
2-propanol will be oxidized to acetone with a distinct smell and will not change the pH.
(H3C)2CHOH → ox → H3C-CO-CH3

Balanced equation:
2C3H7OH + 9O2 → 6CO2 + 8H2O
So, the consumption of propanol and production of carbon dioxide are in the molar ratio 2 : 6, which simplifies to 1 : 3.
Moles of propanol used = 3.49 mol
Moles of carbon dioxide produced = 3.49 mol x 3
= 10.47 mol of CO2 (answer)
