option d Na3AlF6 acts as solvent not electrolyte
According to me it acts as both.
@Gaurav_Singh halogen aur d bock done mein aa sakta hai
why will option (c) not participate in acid-base reaction?
ans given is (C)…
but this link says contrary— My organic doubts - #680 by Dexter27
which one is correct now?
It should be B right
OCH3 doesn’t have such a good acidic hydrogen to get removed.
Answer is (B)
C option me ye FG konsa hh? OCO3H toh pehli baar dekha maine
full form pls
they mistyped the option…its och3 (just searched the q)
nvm then this q no longer remains doubt
-OH is ortho para directing group then. One one ortho position ch3 is there and on the other ortho position steric hindrance will be there so only option is para… But in c option it is getting attached on meta position…how?!
In the last line of the solution how did we get the expansion of ln term also is there any shortcut for this ques if we dont remember expansion
This was in pg advanced illustration i guess u can refer that
An unknown metal of mass 192 g heated to a temperature
of 100°C was immersed into a brass calorimeter of mass
128 g containing 240 g of water at a temperature of 8.4°C.
Calculate the specific heat of the unknown metal if water
temperature stablizes at 21.5°C. (Specific heat of brass is
394 J kg–1 K–1) [10 Jan. 2019 II]
(a) 458 J kg–1 K–1 (b) 1232 J kg–1 K–1
(c) 916 J kg–1 K–1 (d) 654 J kg–1 K–1
Aisi calculations ko karna hi padega kya? Jaan nikal gayi meri iski calculations me…
