10) Reason the solubility of Csl being less soluble than CsF; and Lil being more soluble than LiF in water.
Lit is a hard lewis acid and has a stronge bond to the hard base F in LiF. The opposite is true for Cs* which
is a relatively soft acid and has a stronger bond with the soft bae I”. so, Csl being less soluble than CsF; and
Lil being more soluble than LiF in water.
a) Electronegtivity of the central atom decreases then the bond angle decrese.
so, the bind angle order is Pl; > Asl3 > Sbl3
so, the smallest bond angle is for Sbl
b) Electronegativity of the surrounding atoms decrease (central atom remains the same) the bond angle
so, the bond angle order is OSeF2 < OSeCly < OSeBry so, the smallest bond angle is for OSeF
