Question

Question 5 (1 point) Which one of the following molecules has a permanent dipole moment? O) PbCl4 O) PF5 * O) CS₂ O) F20 O) BF3

Answer 1

Ans ') pbclu - The geomet of the pbel is tetaheoh So thet t s symmetoiceul molecle having zero hence pbcly not having the dipole moment Perment dipole mament PFs Pfs doe not having the perment dipole Moment. The elechoregativity of five fluorine - Phosphorus bonds cancel each other and non-Polcr molecule beaome molecule eohich does not poses CS2 Cs2 net dipole moment. t is a lineor molecule. It does not poesels ferment dipole moment The dipole and huving 4 F20 Foo molecule fa bent moment do not Cancel each others the esulttant dipole moment for the molecule hence F20 is having perment dipole moment dipole momercr equal to Zew BF3 Bfg ha a because tree fluorine veultunt dipole canrel each other and rejultelnt dipole of ang teoo Cancel hird yeultant dipole. hence doe not passe pemment dipole moment
