2gh

u know dielect cons connect 2 plates in parallel . find capacitance as fn of E and current or charge at any inst. integrate from time 0 to t.

u can get the ans. very lenghthy quest.

it ud be good if we dont waste time in integrating and calulating it only process is imp.

NOTE: E remains cons so pot diff is const. only C changes so current is changing

i am sendin many ans but of no use. so if u like it plz. rate i am forced to say....

crack is right but

what if an nitro grp is present which one will be prefered

no2 because of alphabet or because of heaviness

many factors contribute that anyone will act as base or nu-

steric hind, polarity of sol, prod. formed after react their stab, catalysts,path to be followed sn1 sn2 e1 e2 or any other

when it acts as a base it means it has stong affinity towards H+. hence removes h first then alkene is formed

but when it acts as nu- it will replace halogen as usual substituion mechanism

hope i m clear to u

some catalysts like ni pd r used to activate as u know in kinetics,

others act as poison... baso4 to reduce reactivity

catalysts never initiate or change reaction.....

yes ur ans cant be sayed wrong but still hg has very strong tendency to go to hg2^2+ state

here hg is already in stable state

so i dont think there is furthr reactn

doesn solubolity increase down the grp.

plz. give the concept behind it

plz. explain 2

agf is more ionic thats why sol. i think (using fajans rule)

4.ans given is true

fndz.

there r some quest that r tauntin' me.....

*from hot sat. sol. of KNO3 & NaCl which will ppt first-

1.KNO3 2.KCl 3.NaNO3 4.NaCl......

i have prob. between 2 and 4

* the gas that can be liquified at ordinary temp. by app. suitable press.-

1.N2 2.Cl2 3.O2 4. Ar

*when CCl4 burns in air doesnt it give phosgene????

*r all silver halides insoluble?

*t or false?

11.2 l of Oxygen r liberated at anode when 1 fard. of elect. is passed through acidulated water.

i have never really heared of KO3. but considerinng all other opt. definitely a is the ans

dont make the mistakes i have done

dont waste time on thinking which book is best. just read chapters which u think r given the best in a book. conc on atmost 2 books...

systematically solomon is the best. good in conncepts and to the point for complete understanding

simply it is the amount of distortion or charge separation in molecule. more the charge sep less stable and more reactive is the molecule...

but remember with greater dipole moment the mol can be very stable in polar solvents. i hope u can understand this

o yaar r these resonating structures..... i dont think so

still if u want me to choose definitely 1 is ans. AS a is most stable

great achievement,

really proud to have u with us

CONGRAAAAAAATS

chetan and mukulss r right

may be ans given is wrong

the ans must be B

i thought abt it ozonolysis but there is a problem- two carbonyls will appear on acetaldehyde and one is diff to remove keepinf other ald group

controlled ozon. is also not the sol.

u r constantly stressing on screening effect but see my 3rd reply plz.

i think i can be wrong bcoz of both high Z and +screening effect.

but what akhil said is for orbital vel. it is not correct

svj - good ex. it made me clear about what u want to say

i have given my reasons.. dont pound on me plz. am a new kid...

if u r right then u have given me a great knowledge. i was confused becos we r talking of outermost e.

thanks

but still i will consult teachers

well u may be right but i am not convinced...

the lack of screening effect cant be that huge to differentiate between H and Au.

they r not elements close enough to be compared..

shall we ask forum expert or shall we wait for others to reply...

OR r u totaly sure of ur answer.....

yes i agree
