Once you find a carbon atom that is connected to four groups different from each other, that carbon atom is a chiral centre.
Carbon connected to only three or even two groups cannot be a chiral centre.
In a moderately complex molecule, there could be more than one chiral centre. :)[/
Does it have to do anything with d+ and d- ...
and when calculating enthaply change for example in reaction : Ca(s) + 2H2O(l) = Ca(OH)2 (aq) + H2 (g) and u r given Q, which moles do u take from Ca or H2O ?? :D Thanks so much

what is mineral acid ? :S

An acid that has a mineral bonded to a hydrogen. Like H2SO4 (sulfate is a mineral, hence sulfuric acid is a mineral acid); or HCl (chloride is a mineral, hence HCl is a mineral acid) and HNO3 (nitrate is a mineral, hence nitric acid is a mineral acid).

But that's not the actual definition, just my understanding. The actual definition is; 'A mineral acid (or inorganic acid) is an acid derived from one or more inorganic compounds.'

Hope that helps insha'Allah!

Someone in the thread that got closed said that Chlorides do not undergo disproportionation in water and that only happens with NaOH. The former is true, but the latter is not.

Chlorides undergo hydrolysis in water. Chlorine (not chloride), on the other hand undergoes disproportionation in hot alkali, cold alkali as well as water.

Good luck everyone who hasn't given their exam yet! :D
