Question

Which of the following statements about the synthesis of ethylnaphthyl ether are true? Check all that apply.

Tetrabutylammonium bromide carries the alkoxide ion from the water layer into the organic layer so that the SN2 reaction can occur.

The product, ethylnaphthyl ether, will be isolated from the top layer.

If the synthesis is successful, the IR spectrum of the product, ethylnaphthyl ether, will show a broad, strong peak from 3400 - 3200 cm-1.

The SN2 reaction occurs in the aqueous phase.

The reaction system involves two immiscible layers.

correct answers:

(a) Tetrabutylammonium bromide carries the alkoxide ion from the water layer into the organic layer so that the SN2 reaction can occur.

(b) The product, ethylnaphthyl ether, will be isolated from the top layer.

(e) The reaction system involves two immiscible layers.

explanation:

(a) SN2 reaction occur in organic layer which is top layer in this synthesis

(b) top layer less denser organic layer . ether present in this layer . so it is correct

(e) The reaction system involves two immiscible layers. one is organic layer another one is aqueous layer

wrong answers explanation :

(d) sn2 reaction always occur in non-aqueous media . so it is wrong.
