Which of the following is thecorrect order for increasing bond angle ?

Answer»

`NH_(3) LT PH_(3) lt AsH_(3) lt SbH_(3)`
` H_(2)O lt OF_(2) lt CI_(2)O`
`H_(3)Te^(+) lt H_(3)SE^(+) lt H_(3)S^(+) lt H_(3)O^(+)`
` BF_(3) lt BCI_(3) lt B Br_(3) lt BI_(3)`

Solution :`H_(3)Te^(+)ltH_(3)S3^(+)H_(3)S^(+)ltH_(3)O^(+)`
(here, bond angle depends on electronegativiy of central atom )
