Question:
The reaction $R$ -OH + Na $\longrightarrow$ RO$^-$ Na$^+$ + $\frac{1}{2}$ H$_2$ (g) suggests that alcohols are:
The reaction $R$ -OH + Na $\longrightarrow$ RO$^-$ Na$^+$ + $\frac{1}{2}$ H$_2$ (g) suggests that alcohols are:
Show Hint
Alcohols are basic as they can donate a proton (H$^+$) and form alkoxide ions (RO$^-$) in the presence of sodium.

- Acidic
- Basic
- Neutral
- Amphoteric
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The reaction shows that alcohols react with sodium metal to form alkoxide ions (RO$^-$) and hydrogen gas. This indicates that alcohols are basic in nature, as they are able to donate a proton (H$^+$) in the reaction.
