Question

how many are chiral? would it be 4

how many are polar? would it be 5

howmany are non-centrosytemetric ?

im not sure, please help :)

Answer 1

Chiral Molecules Molecules which do not possess any place of synometry or cute of symmetry or 1 inproper axis of siyunnety (Sn). From the given list, only the molecules with point groups O, and C are chiral Ansever i 2 Polar Molecules - Molecules with centre of Symmetry (1) or H-fold inpropets axis of Symmety (54) with Same ligands are non-folar. 4. The midlecules with point groups ,, G , Cs, Cav slar, . Con are polar. (Answer is 6) and the rest of the point groups Den (i) 0u = $30 (telinule, men Polo Den (i) Doh (i) Td S4 (identical ligands) On ni+ Sm

Non-Centrosymmetric ! Molecules which do not possess any centre of Segunetry (2) from the list, such points groups are P , G , Cs, Czy , C3v , Cov, Answer is Td
