Q.5 - Is it C ? I remember reading about it somewhere that in Ziegler Natta Catalyst the alkyl Aluminum compounds attack the monomers.
Q.2 - Is it A ?
I think 2 is A as well
Also bro blood is a buffer na. H2CO3/HCO3-
So what should we write?
Actually answer given is Ti (III) but the explanation says (Et)3Al.
Even I thought A. They say answer is both A and B.
Like Haemoglobin is positively charged sol but answer says blood is negative colloid.
Blood also contains haemoglobin which a is positively charged colloid.
oh ok @Viraam_Rao
Ya Zingler Natta Catalyst is Et3Al, it is in polymers. High Density polymer synthesis maybe
It should be A for question 2 otherwise the second option should be Fe((CO)5 which is used nowadays
@Viraam_Rao class 12 part 1 page 233
“TiCl4 and Al(CH3)3 forms basis of Ziegler catalysts used to manufacture polyethene”
Is it possible options are wrong? It’s neither Ti+3 nor Et3Al. What’s the source??
Organolead compounds are antiknock derivatives, isa kuch padha tha. S block.
Yeah they were used previously but due to the harmful emissions of lead gases nowadays It is replaced by other compounds
Yes Fe(CO)5 is one such
Some coaching teacher told me
Yeah vo ha S block mein .Na/Pb alloy usage.
But wo carbonyl compound ka kya?
Ohh ok. So Ni(CO)4 is definitely not used.
Us hisaab se option Ti III is most appropriate.
Then maybe Ni(CO)4 is also used as antiknock?
Milk wala formaldehyde hai
Haan can u tell me page no from NCERT. I remember reading it somewhere but don't know which chapter? Formalin na?
I’ll try to find it, wait. I just googled.
Isn’t formalin used for preserving dead specimens in lab? Time to stop drinking milk
LOL. I must have gotten confused. I remember reading formalin somewhere and something about milk preservative as well.
Maybe it is used.
This is what wikipedia tells. I too don't remember Ni(CO)4 being used.
Ok Then answer for Question 2 is wrong right. Only option A.
Formalin 40% formaldehyde hota hai
Preservation of milk kaha hai ncert mein, I dont even remember reasing this.
Formaldehyde ke uses mey nahi hai. Part 2 page 365 class 12.
