In compounds of formula E C l 3 , where E = B , P, As or B i , the bond angles C l - E - C l for different E are in the order
Options
- AB > P = A s = B i
- BB > P > A s > B i
- CB < P = A s = B i
- DB < P < A s < B i
Correct answer
B. B > P > A s > B i
Step-by-step solution
B > P > A s > B i As we go down the group bond angle decreases because repulsion between bonded pairs of electron decreases.
