Bhaiya physics aur chemistry ke liye bhi bio ki tarah live session mein 100 -100 most expected questions karwao hamari practice aur boost ho jayegi humble request 🌼 THANKYOU BHAIYA 😊
भईया हम बिहार से है और हम 12th बोर्ड एग्जाम 2024 दिए है बिहार बोर्ड से और मेरा टोटल नंबर 289 है और फिजिक्स में ग्रेस माक्र्स लग गया है (4) नम्बर और फिजिक्स और केमिस्ट्री और बायोलॉजी मिलाकर के हमको 168 नंबर आता है और हम obc कैटेगरी से है तो क्या mbbs काउंसलिंग में हमको निकाल देगा किया और mbbs मे एडमिशन नहीं होगा भईया प्लीज बता digye भईया प्लीज
Hey bhiya I really want to thank you i totally lost the hope tht i will score good enough to crack mbbs I thought i will get only bds but after watching your video i got little motivated tht atleast i will cover bio at my best i tried your strategy though i was not able to cover whole syllabus but i covered my maximum and revised whole 11 th biology from ncert and important chapter of 12 th bio and physics I revised all formula and chemistry also i revised organic inorganic nd physical briefly nd mra kch abi 622 k score bnra nd mre mock m 530 se 560 m are th
Plz make a video on how to manage everything during exam As we all know 2 saal ki mehnat us 3 hour pe depend krti h Usko acche se handle krna bahot jruri h So plz tell us🙏
This man is so constant 😮 raat raat bhar he's making questions just for us n being so updated everyday ❤ luv u sir 💕 thanks 🫀you just give me strength day by day 🎉❤
sir for lap revision shoulld we watch the one shot full zoology and botany video which is to be on yt in thee upcoming days or should we self study???? pls tell sir
@@neetpreparation7829 abhi toh mei khudse hi revision karna prefer karungi kyuki mei padti hi puRA din 11-12 ghnata hu usme agar mei yt dekhiungi toh pura din ek hi subject karte rhe jaungi☠☠
Bhaiya chemistry ki ncert nhi padi h except block or ab Puri padne ka time nhi h .....can u pls tell about the chapters essential to be studied from chemistry ncert

Who is following this timetable today?
Chlo bhailog group 16 revise karvata hu :
1)Most abundant on Earth is Oxygen ( 46.6 % by mass )
2) Abundance of sulphur is 0.03 - 0.1 %
3) Bcoz of conpact nature Oxygen has least electron gain enthaply
4) Stability of +4 Oxidation state increasea down the group and +6 ki decrease hoti down the group
5) Acidic charactee of hydrides : Down the group increases
6) Thermal stability decreases down the group bcoz Bond dissociation enthalpy of hydrides decreases down the group
7) Reducing character increases down the group ( isko mai bond dissociation se relate krta hu ydd rakhne ke liye )
8) M.P and B.P order : H20 > H2Te > H2Se > H2S ( Tellurium aage aya bcoz of Vander walls forces )
9) O3 and SO2 gases aur SeO2 is solid
10) SO2 is most reducing and TeO2 is oxidising ...mtlb down the group reducing charcter decrease
11) Oxides types: EO2 and EO3
12) Amonst hexahalides , only hexadluoridss are the stable ones , yeh sab gases hote hai , sabki octahedral geometry aur SF6 kuch jyada hi stable hota for steric reasons
13) Tetraflourides : SF4 is gas , SeF4 is liquid, TeF4 is solid , sabki sp3d hybridization aur tri-bipyramidal air sabse imp the lone pair of electron occupies "EQUITORIAL POSITION"
aur haa sabki see - saw geometry
14) All elements except oxygen forms dichlorides and dibromides ,
15) yeh dihalides have sp3 hybridization and tetrahedral geometry
16) monohalides exist as dimer in nature and undergo disproportionatiom reaction jaha par change +1 se +4 ka hota hai
Note : monohalides mai doh halogen atoms hote ( eg : S2F2 , Se2Cl2 ) phir bhi inko monohalides kehte hai
17) inke Halides ki stability decreases in the order : F- > Cl- > Br- > I-
Ho gaya , isse bahar nhi jayega 😉
Ek jgh likha h reducing agent down the group increase or ek jgh likha h down the group decrease shi kya hai?
