1.	Which is the correct increasing order of acidic strength from the following of Methan, Ammonia, Water and Hydrogen flouride.
Answer» `HF GT gt H_2O gt gt NH_3 gt gt CH_4` `CH_4 lt lt NH_3 lt lt H_2O lt lt HF` `HF lt lt H_2O lt lt NH_3 lt lt CH_4` `CH_4 lt lt HF lt lt H_2O lt lt NH_3` Solution :`HF gt gt H_2O gt gt NH_3 gt gt CH_4` `LARR` A ELECTRONEGATIVITY increases `larr` `larr` So, acidic strength increases `larr` Where ,A=F,O,N,C
