Chemistry: Post your doubts here!
Thanks Nibz :D Another question At which stage is the oxidation state of Nitrogen different to the changes in the other steps NO3- (aq) -----------(A)----> NO2- (aq) ----(B)--> NO(g) ----(C)--> N2O(g) -----(D)--> N2(g) so in A its +5 to +3 in B +3 to +2 in C it's +2 to +1 in D it's... -
Chemistry: Post your doubts here!
Although one might expect hydrogen bonding to occur between Hl molecules. However, Iodine is too large, and thus the lone pairs are too diffuse ie. not concentrated enough, and hence hydrogen bond attractions between l's lone pairs and hydrogen atoms can not form. answered it for myself hehe -

yes i know this. but Iodine has a negative dipole so won't it form a hydrogen bond with the neighboring Hydrogen (+ve) in the neighboring HI? -
Chemistry QUESTION
Which of the following has dipole-dipole interactions between its molecules, but no hydrogen bonding? A Methane, CH4 B Methanol, CH3OH C Ammonia, NH3 D Hydrogen iodide, HI the answer is D how can it be D? I know the 2 have permanent dipoles and form Hydrogen bonds . A has no dipole. but how is... -
