The correct statements among (a) to (d) are: (a) Saline hydrides produce H _ 2 gas when reacted with H _ 2 O . (b) Reaction of LiAl H _ 4 with B F _ 3 leads to B _ 2 H _ 6 . (c) P H _ 3 and C H _ 4 are electron - rich

Question

Quantrex Academy · Accepted Answer

Correct answer: D. (a), (b), (c) and (d)

(1) Saline hydrides are ionic hydrides such as

LiH, NaH .

When reacting with water to form a Base and hydrogen gas.

MH\left(s\right) + {H}_{2}O\left(aq\right) ⟶ MOH\left(aq\right) + {H}_{2}

(2)

B{F}_{3}

when reacts with

LiAl{H}_{4}

produces

{B}_{2}{H}_{6}

(3)

The correct statements among (a) to (d) are: (a) Saline hydrides produce H _ 2 gas when reacted with H _ 2 O . (b)

(4) Molecular hydrides are also called covalent hydrides.

HF

and

C{H}_{4}

are covalent or molecular hydrides.

Hence, all statements are correct.

The correct statements among (a) to (d) are: (a) Saline hydrides...
