Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

sourav...Do you know the three factor determining the basicity of amine??
Inductive, hydration, steric
Yes then where you have confusion
sir ethyl k case mai.. 1 no key mai dia hai k 3'>0 but 4th key mai dia hai 0 > 3' ethyl.. how?
see this
Sourav jaise size increase hoga steric factor dominant hoga
jaise R= tert butyl hoga to order ho jayega 0>1>2>3
yes sir.. but us qs ka answer kya hoga order ka
kon sa
jo send kiye ho?
yes
sourav thora mixed ho jata hai iss case me...kyunki acid or base thora experimental bhi determine hota hai so pkb values bhi consider hota kabhi kabhi or....koi exact reason nhi mil pata hai ki kiska kon sa effect kitna dominant hai
2nd amine to overall jyada basic hota hai by considering all factors
ethyl ka inductive jyada hai so 2°' jyada hai 2° se
fir 1°' ka 1° se
sir im asking that in key no 1, it is given ethyl 3'>NH3 but in key no 4 it is given NH3> ethyl 3'...why?
Yes wahi na bola exact batane me confusion aa jata hai...kyunki pkb value consider krna par jata hai
to phir real order kya hoga sir
individually ethyl ke case me 2 3 1 0 ye order ekdm correct hai
so go with this
one more qs sir.. ye sare case hum polar solvent leke solve kr rahen hai na.? gas phase or nonpolar lenge to alag ayega?
haa gaseous phase me to totally inductive effect ka case rahega
but hamesha tmhe combination of factors hi milenge
