$N a B H_{4} + I_{2} \to X + Y + Z$
${BF}_{3} + {LiAlH}_{4} \overset{450 K}{\to} X + P$
$B F_{3} + L i A l H_{4} \to X + Q + R$

X, Y, Z, P, Q and R in the reactions are

Options:

X	Y	Z	P	Q	R
$N a_{4} B_{4} O_{7}$	NaI	HI	HF	${AlF}_{3}$	LiF

X	Y	Z	P	Q	R
$B_{2} H_{6}$	NaI	$H_{2}$	NaF	$LiF$	${AlF}_{3}$

X	Y	Z	P	Q	R
$B_{2} H_{6}$	$B H_{3}$	NaI	$B_{3} N_{3} H_{6}$	$A l_{2} F_{6}$	$A l F_{3}$

X	Y	Z	P	Q	R
$B H_{3}$	$B_{2} H_{6}$	$H_{2}$	$B_{3} N_{3} H_{6}$	LiF	$A l F_{3}$

Answer:

Solution:

$2 N a B H_{4} + I_{2} \to \underset{(X)}{B_{2} H_{6}} + \underset{(Y)}{2 N a I} + \underset{(Z)}{H_{2}}$
${2BF}_{3} + 6NaH \overset{450 K}{\to} \underset{(X)}{B_{2} H_{6}} + \underset{(P)}{6NaF}$
$4 B F_{3} + 3 L i A l H_{4} \to \underset{(X)}{2 B_{2} H_{6}} + \underset{(Q)}{3 L i F} + \underset{(R)}{3 A l F_{3}}$
