Cu arrow Cu +, Cu 2+ arrow CuCl , CuF 2 generally transition metals form binary compounds with halogens but Cr form CrF 3 ⇒ MF 3 type compound

Q. Transition elements form binary compounds with halogens. Which of the following elements will form $M F_{3}$ type compounds?

$C r$

$C u$

$N i$

All of these

$C u \to C u^{+}, C u^{2 +} \to C u Cl, C u F_{2}$
generally transition metals form binary compounds with halogens but $C r$ form $C r F_{3}$
$\Rightarrow M F_{3}$ type compound
