Arrange the following alcohols in order of increasing reactivity towards sodium metal.
$(i)$ $C H_{3} O H$
$(i i)$ $(C H_{3})_{2} C H - O H$
$(i i i)$ $C H_{3} C H_{2} O H$
$(i v)$ $(C H_{3})_{3} C - O H$

Question

Arrange the following alcohols in order of increasing reactivity towards sodium metal. ( i ) C H 3 O H ( i i ) ( C H 3 ) 2 C H - O H ( i i i ) C H 3 C H 2 O H ( i v ) ( C H 3 ) 3 C - O H

TestHub · Accepted Answer

More the number of methyl groups (electron releasing) lesser will be the acidity. Hence the reactivity order towards sodium metal will be as follows
tertiary (i) < secondary (ii) < primary (iii).
$(C H_{3})_{3} C - O H < (C H_{3})_{2} C H - O H < C H_{3} C H_{2} O H < C H_{3} O H$
