Physical, organic and inorganic doubts, answered by students.
Bhai bonding chapter ne confuse kar diya. Lewis structure draw karna theek hai, but formal charge pe atak gaya. Ozone: I drew O=O–O with the central O having one double bond and one single bond and a lone pair. NCERT say
Gattermann or Gattermann-Koch? Rosenmund or Stephen? A system for named reactions that survives revision.
Naming rules, the types of isomerism, hybridisation and magnetic behaviour: a sensible boundary for a short chapter.
Boards are around the corner and I am still losing marks on amine classification, which is honestly embarrassing for a "toppers' list" student 🙃 Today's confusion: CH 3 3C-NH 2 . The carbon attached to N has three other
Naming haloalkanes drove me slightly mad today and I need a clean rule set. Here is where I keep losing marks. 1. Numbering: when the chain has a halogen and a methyl, which one decides the direction of numbering? For CH
I made a checklist of oxidation number rules of course I did and applied it to a few compounds from NCERT. It all worked nicely until I hit two cases. In Na 2S 2O 3 : 2 +1 + 2x + 3 -2 = 0 , so x = +2 . In Fe 3O 4 : 3x +
I have been staring at this one for almost an hour and I would like to understand it properly rather than memorise a formula. The problem: a 2 M aqueous solution of glucose M = 180 g/mol has a density of 1.2 g/mL. Find i
Third attempt, so I'm rebuilding organic from zero with a pencil and a very old notebook. Nomenclature is the part I thought I knew and it turns out I don't. Two structures from a practice sheet: A: CH 2=CH-CH CH 3 -CH 2
I'm making my lanthanoid vs actinoid comparison table obviously with colours!! and I got stuck on the oxidation state row. NCERT says lanthanoids mostly show +3, with +2 and +4 only in a few cases, while actinoids show a
ahh I love bio-ish things in the chemistry book but the biological importance part of s-block is just a pile of facts that all sound the same to me 😭 Everyone does "nerve signals" or "enzymes" or "bones". What I have so
Amma says I study best at 5 am with filter coffee, so here I am with thermodynamics, and the very first page of it is eating me. NCERT says internal energy U is a state function while heat q and work w are not. I can rep
SF4 or XeF4, sp3d or sp3d2, bent or pyramidal: one method that works every time.
