Consider the following statement and arrange in the order of true I false.
S1 : In SnCl2 the bonding takes place in ground state and the bond angle Cl−SnCl is slightly less than 120∘.
S2 : The molecular geometry of XeF+7 is pentagonal bipyramidal having two different Xe−F bond lengths.
S3 : In SF4, hte bond angles instead of being 90∘ and 180∘ are 89∘ and 177∘ respectively due to the presence of a lone pair.
