Question

Which of the following is not an electrophile?

1) H+ 2) CH2 = CH2

3) BF3 4) Fe3+​

Answer 1

Answer:

The answer is-

4) Fe3+

hope this will help

Answer 2

$CH_2=CH_2$ is not an electrophile.

• An electrophile is a positively charged or neutral species that possess vacant orbitals to accept electrons.
• Electrophiles are electron loving species.
• $H^+, Fe^{+3}$ are positively charged species so, these are electrophile.
• $BF_3$ has a deficiency of electrons due to the presence of three electron-withdrawing F atoms. So, it also acts as an electrophile.
• $CH_2=CH_2$ has $sp^2$ hybridised C atom which has 33% s character so, it does not act as an electrophile.
