Consider the following reaction,

$ethanol space rightwards arrow with PBr subscript 3 on top space straight X space rightwards arrow with alc. space KOH on top space straight Y space rightwards arrow from left parenthesis ii right parenthesis space straight H subscript 2 straight O comma space heat to left parenthesis straight i right parenthesis space straight H subscript 2 SO subscript 4 of space straight Z semicolon$
the product Z, is

CH₂ = CH₂

CH₃CH₂-O-CH₂-CH₃

CH₃-CH₂-O-SO₃H

CH₃CH₂OH

Solution

CH₃CH₂OH

i) PBr₃ is a halogenating agent, ie, converts -OH group into -Br
ii) Alc. KOH is a dehydrohalogenation agent.
iii) H₂SO₄ and H₂O converts an olefin into alcohol

$straight C subscript 2 straight H subscript 5 OH space rightwards arrow with PBr subscript 3 on top space straight C subscript 2 straight H subscript 5 Br space space rightwards arrow from negative KBr comma space minus straight H subscript 2 straight O to Alc. KOH of space CH subscript 2 space equals space CH subscript 2 rightwards arrow with straight H subscript 2 SO subscript 4 on top space CH subscript 3 minus CH subscript 2 OSO subscript 3 straight H space rightwards arrow from negative straight H subscript 2 straight O to straight H subscript 2 straight O divided by increment of CH subscript 3 CH subscript 2 OH$
