Incorrect statement is:

(a) AlF3>MgO>MgF2    : Lattice energy

(b) Li>Na>Al>Mg       : Electon affinity

(c) SF6>PF5>SiF4       : Lewis acidic character

(d) SICI4>SiBr4 >Sil4   : Decreasing

(c) Correct order of lewis acidic character: PF5>SiF4>SF6 Although, S has vaccant 3d-orbitals but it cannot accept co-ordinate bond from Lewis base due to steric crowding factor as S-atom is already bonded to six F-atoms.
