Answer 1

TABLE 1

FORMULA	TOTAL VALENCE ELECTRONS	MOLECULAR GEOMETRY/ELECTRON GROUP GEOMETRY
I3-	6	because of 3 lone pairs and 2 attached atoms molecular geometry is linear and electron pair geometry is trigonal bipyramid.
OCl-	14	bent
SiF4	silicon has 4 valence electrons and fluorine has 7 total=4+7*4=32	Tetrahedral
NOCl	Nitrogen has 5 valence electron Chlorine has 7 and Oxygen has 6 total=5+7+6=18	Bent or Angular. This is due to the charge distribution on central atom.

Table 2

FORMULA	BOND POLARITY	MOLECULAR POLARITY	MORE SOLUBLE IN WATER OR HEXANE
I3-	I-I bond electronegativity difference = 2.7-2.7=0	neither polar nor non-polar because it is an ion not a molecule and ions itself are charged	I3- is more soluble in water due to ion and dipole interaction between the I3- ions and water molecules.
OCl-	O-Cl bond electronegativity difference = 3.4-3.2=0.2	polar bond is present. O---->Cl	as per like dissolve like OCl being polar dissolves in polar only
SiF?4	bond polarity= electronegitivity of Si -electronegitivity of F=1.9-4=2.1	Though Si-F bond is polar but the SiF4 molecule isn't polar because the 4 bonds cancel the effect of each other.	like dissolves like so non-polar SiF?4 dissolves in hexane.
Cl S O 3 NOCl	bond polarity between N-O=electronegitivity of N-electronegitivity of O= 3-3.4=0.4 bond polarity between N-Cl=electronegitivity of N-electronegitivity of Cl= 3-3.2=0.2	NOCl is a polar molecule. O<-N->CL	being polar more soluble in water4
