Question

Which of the following statements about halides of group 15 elements is incorrect ? (A) Phosphorus and the heavier elements As, Sb and Bi react directly with halogens (B) Phosphorus can form all the pentahalides as well all the trihalides (C) As, Sb and Bi primarily give trihalides (D) SbF5, SbCI5 and AsF5 can also be formed

Tardigrade Admin · Accepted Answer

P, Sb, As and Bi directly react with halogens. Sb, As and Bi mainly form trihalides and pentahalides SbF5, SbCl5 and AsF5 which are also known. So the incorrect choice is B. P can form all trihalides but can-t form trihalides but can-t form all pentahalides since PI5 is not known

Q. Which of the following statements about halides of group 15 elements is incorrect ?

Phosphorus and the heavier elements As, Sb and Bi react directly with halogens

Phosphorus can form all the pentahalides as well all the trihalides

As, Sb and Bi primarily give trihalides

$S b F_{5}, S b C I_{5} an d A s F_{5}$ can also be formed

P, Sb, As and Bi directly react with halogens. Sb, As and Bi mainly form trihalides and pentahalides $S b F_{5}, S b C l_{5}$ and $A s F_{5}$ which are also known. So the incorrect choice is B. P can form all trihalides but can-t form trihalides but can-t form all pentahalides since PI5 is not known
