I found your channel just now. I wish i found it earlier, sir. Appreciate your hard work :)

[namehere]

ATOMIC SIZE
increases T to B, decreases L to R

. inert gas have highest radii
. in 3d .. decreases from L to R UNTIL FE then increases from Cu to Mn {Fe=Co=Ni}
. Al= Ga
. 4d= 5d

IONIC RADII
increases from T to B, decreases from L to R

hydrated radius inversely prop to ionic radii
hydrated radius inversely prop to conductivity

IE/IP
decreases from T to B, increases from L to R




. inert gas have highest IE in period
. 2nd period -- exception in Be, B and N, O (baby No)
. 3rd period -- exception in Mg Al and P S
{for all 4 sets IE1 of 1st > 2nd and IE2of 1st <2nd}
. Boron Familu { B>Tl>Ga>Al>In} (mnemonic- W)
. 5d>3d>4d


ELECTRON GAIN ENTHALPY
decreases from T to B, increases from L to R
[ more -ve electron gain enthalpy = more electron affinity ]

. Bete ne na bolkar ladki ko fasaya
. Maine aur Alka ne pyaari si shadi karli
[noble gases and the ones b4 them and Nitrogen have +ve or 0 EGE]
. 3rd period>2nd period
. Cl>F
.O is least in its period


EN
increases L to R, decreases T to B

[EN increases in intervals of 0.5 in 2nd period, H&P- 2.1, C&I&S- 2.5, N-3, Cl-3.1


OXIDE NATURE
non metallic - acidic
metallic - basic

neutral - NO, N2O, CO

ampho- oxides of V, Mn, Zn, Al, Sn, Pb, Be

for oxides of same element, Oxid no. prop to Acidic Strength
for oxy acids . acidic strength prop to Oxid no. (exp H3PO2> H3PO3>H3P04)

I can't believe I studied some chapters directly from your 1 shots crash coures and I'm able to solve all Pyqs!! Sir u r a gem 💎 ( - NEET Aspirant)

[lodelagehai]

fact that I was able to solve almost all pyqs after this 40 min lecture but was unable to do so after 7 hours one shot is..

From sir s comment section it is clear that how sir is serious and caring for their

[muskankumari]

"English wali hindi to padh hi lete hoge." Sir your sense of humour is timeless.😂 Love the way u taught.

[faizanalam]

I'm 2023 aspirant..here after watching lots of one shorts 3hrs 4hrs videos...bt this video is much much better than those bcz all exceptions covered 😢in very short duration 😊 thank u thank you so much pankaj sir 😌 ur best chemistry teacher ❤️

[shaurya_aggarwal_G]

This 40 min masterpiece cleared more doubts than my 2yrs 😅👍🔥
Edit- now i m in iit😎

[mohitlekhwani]

Yrrr...40 mins m PYQ n exceptions....itne m toh hmare yha dobernier triad pdate h🤣
Remaining tym m revise kr lenge exceptions...
Great sir ji....now targeting whole inorganic by this month 🤟
Thanks a lot sir😎

[yashkanadje]

Kya baat hai .a real teacher never of duty.🤟🤟🏿🤟🏻🤟🏾🤟🏽

[lovestreetfoodie]

I was scared that now I have to leave the complete inorganic portion for jee...I tried reading ncert inorganic not worked, tried my coaching notes not worked; tried to rote pyq not worked; tried to watch long session not now a week before jee I luckily discovered this made me solve everything and now I think I can score from inorganic as you so much pankaj sir ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤ you are a rare diamond❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[leepikachauhan]

With a great teacher like you, I was sure that life would be a successful journey but I never knew you will also make the journey to success such a cakewalk. I can’t express my gratitude, Sir!

[chabgeworldr]

fun fact :vedantu unacademy has thousands of live watching and still they does not provide this quality content

Anyone who finds this channel only has two feelings
Regret - For not finding it earlier.
Satisfaction - For having found it now.

kasam se aaj tak kisi teacher se smjh ni aaya detailed lec, one shot pr ye 40 min ke lec ko dekhne ke bdd saare pyqs hogye mza agya sir

[bhargavvenneti]

literal golden videos, no recent ones can even compare
