Question

11.26 How is 1-propoxypropane synthesised from propan-1-ol? Write mechanism of this reaction.

NEETprep Answer:

1-propoxypropane can be synthesized from propan-1-ol by dehydration.
Propan-1-ol undergoes dehydration in the presence of protic acids (such as H2SO4, H3PO4)
to give 1-propoxypropane.

$2 C H_{3} C H_{2} C H_{2} O H \overset{H^{+}}{\to} C H_{3} C H_{2} C H_{2} - O — C H_{2} C H_{2} C H_{2}$
$P r o p a n e - 1 - o l 1 - P r o p o x y p r o p a n e$

The mechanism of this reaction involves the following three steps:
Step 1: Protonation

Step 2: Nucleophilic attack

Step 3: Deprotonation
