Experts,

can u plz post the resonance structures of HF₂^-- ??

Plz help me!!

ramyadiamond

someone plz reply

astronautameya

i think it is a linear H-F-F(-ve)
or a H-F(-ve)=F
i mean a double bond with central F having -ve charge

Omi

ya actually the question is nt clear......

shubham.123

i think F should be central atom so it goes like this:
H-F=F nd formal charge on central F

ramyadiamond

Actually it has a 4-electron 3 centre bonding unit. But i'm unable to make it and there are supposed to be 3 resonance structures for it. So, plz try and help me if u know abt it.

Omi

ohhhhhhhh..... m confused.....can the experts plzzz look into ths matter plzzzz experts rescue us....!!!!! its a call of SOS...!!!!!!

HF2- HAS A LINEAR STRUCTURE WITH F AS CENTRAL ATOM.
H-F-F
THIS IS MY VIEW .IF HELPFUL RATE ME .
INFORM ME ABOUT RIGHT ANSWER

ramyadiamond

Plz try drawing its resonance structures, if u can have an idea of its structure.!!!!

HF2- has a structure of F-H-F with negative charge on one floride and H-H bond with other. It is a 3 center 4 electron bond. And in terms of bond order you can say that there are two HF bonds of bond order half

Sir, can u please post its 3 resonating structures too??

spideyunlimited

see the resonating structures.
there are two H-F bonds of bond order 1/2.

PLZ RATE:)
