Question

How B2H6 is prepared?​

Answer 1

Answer:

Explanation:

How will you prepare Diborane?

2:-In laboratory,diborane is prepared by the oxidation of sodium borohydride with iodine. 3:-In industry, diborane is prepared by the reaction of BF₃ with sodium hydride.

Answer 2

$\bold{B_{2}H_{6} - } It \: is \: the \: compound \: formed \\ \: by \: B \: with \: H \: which \: is \: known \: as \\ boron \: hydrides \: or \: boranes.$

Preparation-

$(i) \: 4BF_{3}+3LiAlH_{4} = > 2B_{2}H_{6}+3LiF+3AlF_{3} \\ </p><p>(ii) \: 2NaBH_{4}+I_{2} = > B_{2}H_{6}+2NaI+H_{2}</p><p> \\ \bold{Note}- Both \: reaction \: will \: take \\ place \: in \: presence \: of \: ether.$

Properties-

• It is a colourless gas.

• It is very highly reactive

• The boiling point of diborane is about 183 Kelvin.

• It reacts with water very instantly.
