Give the correct order of initials T or ...

Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is falese `:`
`(I)` The order of repulsion between different pair of electron is `I_(p)-I_(p)gtI_(p)-b_(p)gtb_(p)-b_(p)`
`(II)` In general, as the number o flone pair of electron on central atom increases, value of bond angle from normal bond angle also increases
`(III)` The number of lone pair on O in `H_(2)O` is 2 while on N in `NH_(3)` is 1
`(IV)` The structures of xenon fluorides and xenon oxyfluorides could not be explained on the basis of VSEPR theory

Text Solution

Verified by Experts

The correct Answer is:
B
(ii) ( F) In general as the number of lone pair of electrons on central atom increases, value of bond angle from normal bond angle decreases due to `lp- lp gt lp - bp`
(iv) (F) Structures of xenon fluorides and xenon oxy fluoride are explained on the basis of VSEPR theory.
In `SOBr_(2), S-O` bond has maximum bond length in comparison to S-O bond lengths in `SOF_(2) and SOCl_(2)`, because in `SOBr_(2)`, S-O bond has been formed by hybrid orbital containing less s-character.
