Question

Explain why propan -2-ol is more basic than propan-1-ol?


please explain it well​

Answer 1

Hint: Methanol is alcohol containing 1 methyl group along with 

1 OH1 OH

 group whereas propan-1-ol is compound with a higher number of carbon chains. This information can easily reveal the answer if linked properly to the concept. 

Step by step explanation:

In the given question, the concept of solubility is asked in which alcohols solubility is compared and we know alcohol is an organic functional group containing 

OHOH

 as a group and the rest is a carbon chain. 

Now the solubility of this alcohol will depend on a few factors which we will discuss. There is a general rule for solubility which is “Like dissolves like” and here we will see how these alcohols are dissolving in water whereas higher alcohols like propan-1-ol does not get dissolved in water.

Methanol is a compound containing alcohol function with 1 Methyl group. So, it has formula i.e. 

CH3OHCH3OH

 and when it is dissolved in the solution, there is hydrogen bonding formed between Methanol and water and as a result it becomes soluble in it. In Methanol, the carbon containing part is non-polar in nature whereas 

OHOH

 is polar in nature.

Becomes soluble due to (R−Oδ−−H

Answer 2

Propanol on loosing a proton become whereas propan-2-ol on loosing a proton becomes . In , two methyl group are present. These methyl group having +I effect on central O^- due to which negative charge increases on oxygen to high enough in comparison to having only one methyl group.
