what is a tropolium ion & its structure.please give some properties

youuknowwwhoo

I think you are talking about Tropylium ion , if it is tropylium ion

In organic chemistry, the tropylium ion is an aromatic species with a formula of [C₇H₇]⁺. Its name derives from the molecule tropane (itself named for the molecule atropine).

It is a heptagonal, planar, cyclic ion; as well, it has 6 ?-electrons (4n+ 2, where n=1), which fulfills Hückel's rule of aromaticity. It can coordinate as a ligand to metal atoms.

The structure shown is a composite of seven resonance contributors in which each carbon carries part of the positive charge.

This fragment is often found for aromatic compounds containing a benzyl unit. On ionization, the benzyl fragment is cleaved off. It (PhCH₂⁺) rearranges to the highly stable tropylium cation (C₇H₇⁺).

lol...............arre bhai .......
its the TROPYLIUM ION...............i hope that's what you are referring to.........

i can tell you how much i know.......
other ppl can elaborate..........
1.) its an AROMATIC SPECIES WITH A
FORMULA -[ C₇H₇]⁺

2.) it follows the huckel's rule of aromaticity( i hope u knw that)

its famous because it acts as a ligand to metal atoms...........

3.)i'm pasting its structure........hope that'll do
