1.	Which of the following regarding diborane is correct ? (I) It is a colourless and toxic gas. (II) It undergoes spontaneous combustion in presence of oxygen forming B_(2)O_(3). (III) It can be obtained by reduction of BF_(3) by following reaction. 2BF_(3)+6NaHoverset(180^(@)C)rarrB_(2)H_(6)+6NaF (IV) It undergoes hydrolysis forming boric acid and hydrogen gas. Correct code is :
Answer» I,II,III,IV II,III III,IV I,IV Solution :`V_(2)O_(5)` preferiably forms oxycation because it is amphoteric METAL oxide.
