Tricks to Remember s-Block Reactions | Part-1 | Jee Mains | Advance | NEET| BITSAT | AIIMS

Hello Guys, In this video we are going to provide some of the awesome tricks to remember s-Block reaction. Since, s-block is one of the most important topic for Jee Mains, Advance, NEET and BITSAT.
In this lecture, we have given a lots of tricks to remember s-Block reactions such as:- (Some Examples)
NaOH is stable towards heat but is reduced to metal when heated with carbon
2NaOH + 2C → 2Na +2CO + H2
FeCl3 + 3NaOH →Fe(OH)3 + 3NaCl
NH4Cl + NaOH → NaCl + NH3 (pungent smell) + H2O
HgCl2 + 2NaOH → HgO (yellow powder) + 2NaCl + H2O
Zn(OH)2 ↑ + 2NaOH → Na2ZnO2 + 2H2Oh
Al2O3 ↑ + 2NaOH → 2NaAlO2 + H2O
SiO2 + 2NaOH → Na2SiO3 + H2O
3P + 3 NaOH +3H2O → PH3 + 3NaH2PO2
2Al + 2 NaOH + 2H2O → 3H2 + 2NaAlO2
2Na2O2 = 2 Na2O + O2 (400-675°C, vacuum).
Na2O2 + 8H2O(moisture) = Na2O2 - 8H2O (0° С).
Na2O2 + 2H2O(cold) = H2O2 + 2NaOH
2Na2O2 + 2H2O(hot) = O2↑ + 4NaOH.
Na2O2 + 2HCl(diluted, cold) = 2NaCl + H2O2.
2Na2O2 + 2H2SO4 (diluted, hot) = 2Na2SO4 + 2H2O + O2↑.
Na2O2 + O2 = 2NaO2 (450-500°C, pressure).
2Na2O2 + S = Na2SO3 + Na2O (100° C)
2Na2O2 + С(graphite) = Na2CO3 + Na2O (100°C)
3Na2O2 + 2Al (powder) = 2NaAlO2 + 2Na2O (70-120°C).
2Na2O2 + 2 CO2 = 2Na2CO3 + O2
Na2O2 + CO = Na2CO3 (normal temp.).
Na2O2 + MnO2 = Na2MnO4 (400-500°C).
Na2O2 + 2Na = 2Na2O (130-200°C, in the atmosphere of Ar).
5Na2O2 + 8H2SO4(diluted) + 2KMnO4 = 5O2↑ + 2MnSO4 + 8H2O + 5Na2SO4 + K2SO4.
Na2O2 + 2H2SO4(diluted) + 2NaI = I2↓ + 2Na2SO4 + 2H2O.
3Na2O2 + 2Na3[Cr(OH)6] (hot) = 2 Na2CrO4 + 8NaOH + 2H2O.
Na2O2 + 2H2SO4 (diluted) + 2FeSO4 = Fe2(SO4)3 + Na2SO4 + 2H2O
Na2O2 + 2Fe(ОН)2(suspension) = 2FeO(OH)↓ + 2NaOH.

Keep Sharing, Keep Supporting!! These reactions are backbone of inorganic chemistry, very helpful to understand passage/paragraph based questions..Bcoz paragraph based questions are linked to many chapters including several reactions. कोई Reaction छोटा या बड़ा नही होता और Reaction के बिना competitive exam crack नहीं होता । 😁😁 Good Luck, Keep Learning. Thanks Team IITian Explains

Sir, Firstly, from the bottom of my heart; thank you. Thachers like you are really helping the masses. Secondly, I have a question: How or more precisely should I study molr concept 2, my logics aren't very clear and I am not confident that I would be able to solve questions during JEE Advance.

Trick bas yahi h ki, option wala h toh ache se approximate karke ese nikalo taaki jyada bada gap Naa aye ans m aur jyada dikkat nhi ho, for ex 75.37×292.43 isko real m toh Nikalna time waste hoga, isko agar 75×295 kardoge toh easily hoga, aur jyada gap bhi nhi ayega real ans main, aur vedic math thoda practice karlo,ho jaega
