Question

Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is false : (I) The order of repulsion between different pair of electrons is lp - lp > lp - bp > bp - bp (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 H2O is 2 while on N in NH3 is 1 (IV) The structures of xenon fluorides and xenon oxyfluorides could not be explained on the basis of VSEPR theory

Answer: B

💡 Solution & 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 decreases due to lp-lp > lp-bp. (IV) (F) Structures of xenon fluorides and xenon oxy fluoride are explained on the basis of VSEPR theory.
