Question

Consider the following reaction,
PBr₃ alc.KOH (i) H₂SO₄ room temperature
Ethanol ➝ X ➝ Y ➝ Z
(ii)H₂O,heat
the product Z is:
(a) CH₃CH₂-O-CH₂-CH₃
(b) CH₃-CH₂-O-SO₃H
(c) CH₃CH₂OH
(d) CH₂=CH₂

Answer 1

Answer:

c

Explanation:

C2H5OH----PBr3--- C2H5Br----KOH-----CH2=CH2---H2SO4----- CH3CH2HSO4-------H2O------CH3CH2OH

Answer 2

pBr3 will give SN2 reaction

C2H5OH ⟶C2H5BR

Alc.koh will give elimination reaction and forms the double bond

C2H5Br⟶C2H4

H2SO4,H30 will give electrophilic addition reaction

C2H4⟶C2H5OH
