In ammonia the bond angle is 107^ 48^ while in SbH ₃ the bond angle is about 91^ 18^ . The correct explanation among the followings is/ areWhich of the following compounds contain 3-centered 2-electron bonding? (i) [ BeF ₂ ]_ n (ii) [ Be ( CH ₃ )₃ ]_ n (iii) [ BeCl ₂ ]_ n (iv) [ BeH ₂ ]_ nIn the Lewis structure of ozone ( O ₃ ) , the formal charge on the central oxygen atom isHClO ₄ is a stronger acid than HClO . The correct statement isThe pair that is isostructural (i.e. having the same shape and hybridization) isAt 25^ C , nitrogen exists as N ₂ and phosphorous exists as P ₄ becauseAssuming that Hund's rule is violated by the diatomic molecule B ₂ , its bond order and magnetic nature will be respectivelyIodine is a solid and sublimes at ordinary temperatures.
