I also want strongest and weakest organic acids?

HF is only a weak acid; its corrosive effects arise from the properties of the F- ion, not the H+. However, it is used to form superacids such as HSbF6, which is 2x10^19 times stronger than H2SO4, probably the strongest inorganic acid.
The strongest organic acid would likely be the carborane superacid; H(CHB11Cl11).
As for the weakest acids, what must be remembered is that an acid (according the the Bronsted definition) is simply a proton donor. So for the weakest acids, what we are after is species which
a) have protons and
b) are very reluctant to give them up
So for an organic compound, the weakest acid would be a salt of the ion HC(3-) i.e methane with 3 protons removed. Methane itself is a pathetically weak acid (pKa of around 60), and it will get progressively harder to remove successive protons (because you are removing a positively charged ion from a negatively charged species).
On the same principle, the weakest inorganic acid would be imide salts; i.e. salts of the HN(2-) ion.

Unfortunately there's actually no way of knowling whether an acid is strong or weak just by looking at its formula. However, there are some tricks you can learn. For example, if it's dissociation with water is written in an equation, a single arrow means it's a strong acid (because it dissociates completely), but a weak acid is shown with double arrows (because it only partially dissociates). Also, the organic acids, which are usually written with COOH on the end of the formula, are all weak acids. For example, CH3COOH (ethanoic acid) is a weak acid. As you do more work with acids, you'll learn to recognise the common ones and learn whether they are strong or weak. Especially with ones like HCl (a strong acid) that come up all the time. Good luck!

strongest inorganic acid is sulphuric acid ,its called the king of all acids. the weakest inorganicacid is phosphoric acid.
stongest organic acid ethonol and weakest organic acid is formic acid.

STRONGEST:-Hydrofluoric ( HF ) acid, one of the strongest inorganic acids , is used mainly for industrial purposes (eg, glass etching , metal cleaning, electronics manufacturing )

Strongest: HF
I think the weakest is H3PO4
...didn't study inorganic chem, so can't help you there.
