1.	Among the following , which one is a wrongstatement ?
Answer» `PH_(5) and BiCl_(5)` do not EXIST ` p pi-dpi` bonds are present in `SO_(2)` `SeF_(4) and CH_(4)` have same shape `I_(3)^(-)` has bent geometry . Solution :`(a) PH_(5)` does not exist whereas `PCl_(5) and PF_(5)` exist This is because Cl and F have p-orbitals to overlap with d-orbitals of P but H does not have p-orbitals . Again `BiCl_(3)` exists but `BiCl_(3)` does not due to INERT paireffect (b) ` p pi - d pi` bonds are present in `SO_(2)` (c) `SeF_(4) = sp^(3) d, lp = 1 ` shape = see-saw ` CH_(4) = sp^(3) , lp = 0` , shape = tetrahedral (d) ` I_(3)^(+) = sp^(3), lp = 2 `shape = bent/angular.
