Question

Match each alcohol with its rank from highest (1) to lowest (3) strength in acid properties.
A) CH3OH 1. ________
B) C4H9OH 2.________
C) C8H17OH 3. ________

Answer 1

Strongest acidic properties has CH3OH,
Weakest acid properties has C8H17OH.

1.CH3OH ,2. C4H9OH, 3.C8H17OH.

Answer 2

Answer:

A) CH3OH 3

B) C4H9OH 2

C) C8H17OH   1

Explanation:

A common alcohol is represented as ROH

Where  = substituent

Here in this the substituents are – CH3, C4H9 and C8H17

As the size of substituent increases, the acid becomes more and more strong. This is so because this makes availability of large volumes over which the charge can be distributed and thus the charge density reduced. Reduction is charge density also reduces the Coulombic repulsion
