Inorganic Chemistry
You are presented with identical metal containers of about 5 liters capacity each about half full of fuel. The containers have short neck and are normally closed by screw cap of about 30mm diameter. The cans contain
1. petrol(gasoline, flaspoint-43 degree Celsius.)
2. methyl alcohol (methanol, flashpoint 11 degree Celsius.)
3. paraffin (keresone, flashpoint 50 degree Celsius.)
Explain concisely what would happen if top was taken off and a lit match was immediately dropped in the head space of each can. Assume the ambient temperature and thus that of liquid is 15 degree Celsius.

Hi!
I have some doubts in coordination compounds. Well I was making the structure of [Ni(CN)4]2- and lost my mind. If we work according to the crystal field theory then (Ni)2+ is d8 configuration which means it will have 2 unpaired electrons in the t2 orbitals. While if we work according to the valence bond theory then the 2 unpaired electrons of Ni2+ have to pair up in presence of strong ligand CN- meaning there are no unpaired electrons. How is this possible? Which is correct? Sorry for my poor English. Hope you reply soon :)
