Vapour pressure is independent of surface area.

[@chachugaming9812]

Sahi BAAT Mai bhi yay Soch Raha tha

[@arhaaansaeed5233]

Vapour pressure is inversely proportional to surface area

[@aqsanawaz6299]

VP is directly proportional to surface area 💯

[@chemistrywithshad4639]

well explain

[@rafiqshinwari4095]

Best explanation done.... Welcome

[@tehseenzahra5126]

Thanks a lot sir

[@tanveerahmed-ne9ix]

Thanks sir 3 question past papers SA aaye te Jo ap ne solve Kiya ta love you sir❤

[@aqsanawaz6299]

Sir catalytic reduction alkene deti ha reducing agents alcohols dete hn

[@shahzadzimri1901]

135lucas test only for alcohol

[@laibanawaz6640]

Sir mujhe doosron ka pta nhi but sir yh vapour pressure book ki line hai independent of surface area
Aur doosri bat ke is dfa test main 2 options mostly ase the jo correct the 😢

[@AbdulQuddoosbutt-ie1zd]

Sir ggg Alcohol lucus test deti he

[@murtazabc8063]

Sir halogenation ni hoskta kiun keh Alcohols bhi conc hbr ke saath react krte to form alkyl halides which is nucleophillic substitution reaction so lucas wala option sb se best hai

[@jawadkhan4646]

bro lucus test can be obly used to deffrentiate alcohols only like primary ,,, secandry and tertiary etc ...bye the way halogenation is correct option accaording to over book kpk ....

[@murtazabc8063]

@@jawadkhan4646 bhai jaan google pr bhi dekh lo aur halogenation to alcohols ki bhi hoti jisme alkyl halides ke formation hoti

[@aqsanawaz6299]

Listen! Phenols can also give halogenation but alcohols can't give nitration. So I guess nitration is the best one

[@jawadkhan4646]

as given in our book so according to that halogenatyion is correct ..kp book
@@aqsanawaz6299

[@Shan_writes101]

@@aqsanawaz6299 correct opt is halogenation...bcz phenol when react with aq KOH it forms white opt but alcohol react with halogen but will not form white ptt.
The opt idoform is wrong bcz only ethanol gives idoform .we can't differentiate all other alcohols by idoform.

[@AyazKhan-zx9kc]

Sir...szambu past papers upload kiye hy aap ny? Chemistry

[@ChemistrybyAdil]

Yes. 2022 wala

[@AyazKhan-zx9kc]

Sir...kindly baqi years k bhi kr dijiye...

[@aqsanawaz6299]

Sir Alcohols itna famous reaction dete halogens k sath ..SN reaction.

[@ChemistrybyAdil]

That's not with Halogen but Halogen Acid.

[@tanveerahmed-ne9ix]

Sir aik request ha k bumhs k past papers solve karey please sir hum Balochistan walo ko koi b value Nahi deeta sir TH-cam ka platform ma ap k liya Kisi ne b past paper upload Nahi ke sir 2021 2020 2019 sab ki past papers karo❤❤❤

[@ChemistrybyAdil]

No dear. I love all Pakistan. Actually bumhs k paper online koi upload ni krta. Not available.

[@shahzadzimri1901]

Sir 1d h

[@mahnoorishaikh]

Sir 114 mai B Q nhi hosakta??bcz crystal to face centred cubic ee hai

[@chineselover8438]

Yes you are right

[@jawadkhan4646]

yup is ma opt A and C dono aatha han ...and ma na pesnolly c teek kiya han

[@musfirahtariq2839]

I think B correct h ku k option 1 Coordination number h or unho ne geometry pochi h

[@linaa_choudhary]

Nhi federal ki book utha k dekho cubic haa...0.44 hotaa only cubic ...CsF is centered cubic

[@Shan_writes101]

NaCl....
Correct opt...Each Na is surrounded by 6 Cl- and each 6 Cl- is surrounded by 6Na
...
Face center is wrong bcz....
NaCl may be face cubic when it is in pure form but when impurity is added then Its structure will be octahedral.....
So structure of NaCl change so face cubic is not opt😊

[@M.faheemKhan]

Sorry sir but nitric oxide jab ozone ke sath react karta hain tu ye 1st order reaction not 2nd order

[@a_majidkhattak]

No you r wrong bro

[@M.faheemKhan]

U can search google
