Do PCl5 have 3 lone pairs for each Cl? and 1 lone pair for P ??

  • Chemistry - ,

    Each Cl has 3 lone pairs but P has no lone pairs.
    P has 5 e.
    Cl has 5 x 7 = 35
    total e = 40
    Count the 6 around each Cl and that accounts for 30 electrons. Then count 10 more for the 5 bonds for each P-Cl and that is the 40 electrons available.
