More stable is alkoxide ion R—O ominus more is the acidic nature of corresponding alcohol. Electron donating (+ I-effect) alkyl groups decreases the acidic strength.

Q. The correct order of acidic strength of the following alcohols is
I. $C H_{3} O H$
II. $C_{2} H_{5} O H$
III. $C H_{3} - C H (O H) - C H_{3}$
IV.

$I < II < III < I V$

$III < II < I V < I$

$III < I V < I < III$

$I V < III < II < I$

More stable is alkoxide ion $R — O^{⊖}$ more is the acidic nature of corresponding alcohol. Electron donating (+ I-effect) alkyl groups decreases the acidic strength.
