Give the correct order of initials T or F for following statements. Use T is statement is true and F if it is false :
(I) The order of repulsion between different pair of electrons is `l_(p)-l_(p) gt l_(p)-b_(p) gt b_(p)-b_(p)`
(II) In general, as the number of lone pair of electrons 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

Options

A. TTTF
B. TFTF
C. TFTT
D. TFFF

Answer

2

Explanation

`(ii)(F)` In general as the number of lone pair of electrons on central atom increases, value of bond angle from normal bond angle dereases due to `Ip-Ip gt lp-bp.`
`(iv)(F)` Structure 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.
