lu
a
2.6 Which of the following reagents will react with furan to form
2-furansulphonic acid ?
SO3 in puridine at 100 °C
b SO2 at 100 °C
c Dil.H2SO, at 200 °C
d Dil.H SO, at 100 °C​

Answer 1

A) so3 in puridine at 100°c

Answer 2

Concept introduction:

An electron-rich species (the nucleophile) will frequently "attack" an electron-poor species (the electrophile, typically a carbocation), creating a new bond between the nucleophile and the carbocation.

Explanation:

Given that, furan and  $2$-furansulphonic acid.

We have to find, the reagents required to form  $2$-furansulphonic from furan.

According to the question,

H$2$SO$4$ performs nucleophilic attack on furan ring and forms $2$-furansulphonic acid at  $200$ °C.

Final Answer:

Option: c Dil.H$2$SO$4$, at $200$ °C.
