  oridochloridotriphenylphosphinepalladiun (II)
• B. $\mu$-Dichloridodichloridobis(triphenylphosphinc)
  dipalladium (II)
• C. $\mu$-Dihloridobis( chloridotriphenylphosphinepallad
  iun) (II)
• D. Bis ($\mu$-chloridochloridotriphenylphosphinepallad
  iun) (II)

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Chloridotriphenylphosphinepalladiun (II) $\mu$-dichl
oridochloridotriphenylphosphinepalladiun (II)
B $\mu$-Dichloridodichloridobis(triphenylphosphinc)
dipalladium (II)
C $\mu$-Dihloridobis( chloridotriphenylphosphinepallad
iun) (II)
D Bis ($\mu$-chloridochloridotriphenylphosphinepallad

iun) (II)
Option (A),(B),(C),(D) are correct.

In this complex chlorido is named first followed by $PP{h}_3$. $Cl$ has -1 charge and $PP{h}_3$ is neutral so charge so first $Pd$ has +2 charge. In this complex two chlorine acts as a bridge so $\mu$ is to be used and second $Pd$ also carries +2 charge. Bridging ligands can also be named first.
