According to Lewis concept of acids and bases, ether is
1 Acidic
2 Basic
3 Neutral
4 Amphoteric
Explanation:
(b) Ether is basic because lone pairs of electrons are present on oxygen atom, \(R - \mathop {\mathop O\limits_{ \bullet \, \bullet } }\limits^{ \bullet \, \bullet } - R\).

The compound which is not isomeric with diethyl ether is
1 \(n-\) propylmethyl ether
2 Butan-\(1\)-ol
3 \(2-\) methylpropan \(- 2-\) ol
4 Butanone
Explanation:
Diethyl ether \(\Rightarrow C _2 H _5 OC _2 H _5\). Meal formula \(= C _4 H _{10} O\) \(\therefore\) Butanone is not isomeric with diethyl ether.

Structure of diethyl ether is confirmed by
1 Kolbe's synthesis
2 Frankland's synthesis
3 Wurtz's synthesis
4 Williamson's synthesis
Explanation:
Kolbe synthesis is a method of synthesizing aromatic \(o-\)hydroxycarboxylic acids (Salicylic acid) by the action of \(CO_2\) on the alkaline salt of the phenol. The preparation of dialkyl zinc from zinc and alkyl iodide is called the Frankland reaction. In Wurtz's reaction, two alkyl halides are reacted with sodium metal in dry ether solution to form a higher alkane. An alkyl halide is allowed to react with sodium alkoxide to form symmetrical and unsymmetrical ether and the reaction is called Williamson's synthesis. Hence, diethyl ether can be prepared using Williamson's synthesis.
