If "CHEMISTRY" students start making films,

*Tera acid mera base
*Rang de benzene
*Humara beaker aapke pas hai
*Life in a Hetero
*Laaga apron me daag
*3 test tubes
*Ajab estimation ka gajab result
*Munna bhai HCL
*Mr. Ketone
*Jab we experiment...!

😜😜Dialogue baazi in chemistry..
*My name is BOND...Covalent Bond!
*Rishtey mein to hum tumhare Allotrope lagte hain, naam hai...Diamond!
*D-block se darr nahi lagta saheb, F-block se lagta hai!
*Ek baar jo maine bond toda to main activation energy ki bhi nahi sunta!
*Resonance ko neglect karna mushkil hi nahi na mumkin hai!
*Ye electron mujhe dede Carbon!
*Ek neutron ki keemat tum kya jano Hydrogen Babu!

To all science students
😂😂😂😂😂😂😂😂
Just for u...
*GUYS THANK YOU FOR SO MANY LIKES AND COMMENT. I NEVER THINK ABOUT THAT MUCH LIKES*

Chlo saathiyon, saath me shuruwat krte hai 2024-2025 Class 11 ki ❤

[maanparashar]

Attendence of class 11th....2024-25🥺
Tnku friends for many likes😢
Itni likes kbhi na hue...143 please like my comment i have dream of 1k on my comment 🤕

[princekr.panjiyar]

Fact - Whole Class 9 chemistry syllabus is in one chapter 💀

[charliomarak]

Anyone who's coming here because we don't understand our teachers teaching 😂

[AnilKumar-byjn]

Kis kisne science side lekar risk liya ha 🤞

[progamingninja]

These are called real teachers who deserve to get their salary for teaching in schools

[prabhatipradhan]

Dear friends let's start together the journey of class 11 batch 2k24-25❤❤ All the best.... Together we can we will❤😊

[mauvehydra]

I remember coming here for revision before my first exams of grade 11. Now that i've passed 12th I'm back at the start for revision for NEET. I found this kind of difficult at that time but now it feels sooo easy. Keep grinding new 11th graders, I hope you all get your dreams

[SashiGrewal]

NEET aspirants attendance here 700+ marks ✌️😎

[StimulativeClasses]

Finally I completed this chapter today .... 7 din lag gye Pura dekhne me 😅😅😅😅😅.. 😂😂
EDIT - THANK YOU MY FRIENDS FOR 1.1K LIKES 🥳🥳🥳🥳🥳
DATE - 1 MAY 2022
