Q. Explain about Monohalides?
Monohalides of the type M2X2, (where X = F, C1 and Br) are formed only by 0. S and Se. Oxygen monofluoride decomposes above 25 K. These monohalides have got structures similar to H2, O2, having E-E bonds.
Monohalides of Te and Po are not formed because Te-Te and Po-Po bonds are not stable. The monohalides are slowly hydrolysed to give the oxoacid,
2Se2Cl2+ 2H2O -------------------> H2SeO2+ 3Se+ 4HCl
Sulphur can readily be dissolved into sulphur monochloride. S2, CI2 to give chlorosulphanp s, such as. S3 CI2 , S4,Cl2 and so on upto S100 CI2.
