Corrrect order of bond angle in the given compounds is/are:

Answer»

`gammaltgamma'`
`gammaltbeta=alpha`
`alphagtalpha'`
`betagtbeta'`

Solution :According to Bent.s rule, there is less s-character in `C-F` bonds in `COF_(2)` than in `C-Cl` bonds in CASE `alphaCOCl_(2)` hence `gamma.gtgamma and angleFCF` is less than `120^(@)`
`alpha=beta` as both `C-F` bonds are equivalent SIMILARLY `alpha.=beta.` as both `C-Cl` bonds are equivalent `alpha=betagtgamma`
`alphagtalpha.`betagtbeta.`
