Question 17

Aqueous solutions of propylamine (CH3CH2CH2NH2\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2CH3​CH2​CH2​NH2​), ammonia (NH3\text{NH}_3NH3​), and phenylamine (C6H5NH2\text{C}_6\text{H}_5\text{NH}_2C6​H5​NH2​) are prepared with equal concentrations at the same temperature.

Which of the following represents the correct order of decreasing pH of these solutions?

C6H5NH2>NH3>CH3CH2CH2NH2\text{C}_6\text{H}_5\text{NH}_2 > \text{NH}_3 > \text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2C6​H5​NH2​>NH3​>CH3​CH2​CH2​NH2​

CH3CH2CH2NH2>NH3>C6H5NH2\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2 > \text{NH}_3 > \text{C}_6\text{H}_5\text{NH}_2CH3​CH2​CH2​NH2​>NH3​>C6​H5​NH2​

NH3>CH3CH2CH2NH2>C6H5NH2\text{NH}_3 > \text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2 > \text{C}_6\text{H}_5\text{NH}_2NH3​>CH3​CH2​CH2​NH2​>C6​H5​NH2​

CH3CH2CH2NH2>C6H5NH2>NH3\text{CH}_3\text{CH}_2\text{CH}_2\text{NH}_2 > \text{C}_6\text{H}_5\text{NH}_2 > \text{NH}_3CH3​CH2​CH2​NH2​>C6​H5​NH2​>NH3​
