Chemical Bonding
Molecule having maximum number of covalent bonds is:
Calculate the value of X-Y, for $$XeOF_{4}$$. (X = Number of $$\sigma$$ bond pair and Y = Number of lone pair on central atom)
$$X=5,Y=1$$
$$X-Y=5-1=4$$

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 the repulsion between different pair of electrons is $$l_{p} - l_{p} > l_{p}- b_{p} > b_{p}- b_{p}$$ (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
