Q. 12.50 - An Introduction to General, Organic, and Biological Chemistry

Question

Which compound in each pair would be more soluble in water? Explain. ($12.2$)

a. $ethane$ or $ethanol$

b. $2-propanol$ or $2-pen\tan ol$

c. $methyl propyl ether$ or $1-bu\tan ol$

Step-by-Step Solution

Answer

(a) The $ethanol$ will be more soluble in water

(b) The $2-propanol$ will be more soluble in water

(c) The $1-bu\tan ol$ will be more soluble in water

Part (a) Step 1: Given information

We need to find that which out of the $ethane$ and $ethanol$ will be more soluble in water 

Part (a) Step 2: Explanation

We know that

The compound which will form more hydrogen bonds will be more soluble in water.

And out of the given compounds $ethanol$ will form hydrogen bonds

Therefore, The $ethanol$ will be more soluble in water 

Part (b) Step 1: Given information

We need to find that which out of the $2-propanol$ and $2-pen\tan ol$ will be more soluble in water  

Part (b) Step 2: Explanation

We know that

The compound which will form more hydrogen bonds will be more soluble in water.

And out of the given compounds $2-propanol$ will form hydrogen bonds

Therefore, The $2-propanol$ will be more soluble in water 

Part (c) Step 1: Given information

We need to find that which out of the $methyl propyl ether$ and $1-bu\tan ol$ will be more soluble in water  

Part (c) Step 2: Explanation

We know that

The compound which will form more hydrogen bonds will be more soluble in water.

And out of the given compounds $1-bu\tan ol$ will form hydrogen bonds

Therefore, The $1-bu\tan ol$ will be more soluble in water
