Consider the following statements.
S1 : The percentage of s-character in the orbital forming S – S bonds and P – P bonds in S8 and P4 molecules respectively are same.
S2 :In SF4 the bond angles, instead of being 90 0 and 180 0 are 89 0 and 177 0 respectively due to the repulsions between lone pair and bond pairs of electrons.
S3 :Aqueous H3PO4 is syrupy (i.e more viscous than water)
S4 :SiO2 crystal may be considered as giant molecule in which eight-membered rings are formed with alternate silicon and oxygen atoms.
Of these :
Text Solution
Verified by ExpertsC
in S8 hybridisation of each S-atom is sp3 , in P4 hybridisation of each P-atom is sp3
due to bp-lp repulsions
Inter molecular H-bonding (PO43– groups are bonded by many H-bonds)
