can u pls explain how 3 cl atoms will cause less dipole moment and as above sti is wrong in telling that the molecule shows geometric isomerism

when there is liquid the lens acts as a planoconcex lens
with R1=R(RADIUS OF CURVATURE OF CONCEx LENS)
R2=INFINITY(PLANE SURFACE)
THE FOCAL LENGHT OF THE COMBINATION IS GIVEN BY;
1/F=1/f1+1/f2
where f1=f of convex lens
f2=focal lenght of liq lens
1/f2=(n-1){1/R1-1/R2)
=(n-1)/R1
in the problem a=F and b=f1 so solve for f2 and substitute it in the eqn and then u'll get an expression for n

in PCl5 p is in its highest oxdn state so it cannot attain any higher oxdn state as it has no electron to donate so it can only get reduced and hence acts as a oxidising agent

which has a greater dipole moment CH2Cl2 or CHCl3 n why?????????
|
|
|
|
why is the order of acidity of oxoacids as follows;
HOCl<HOClO<HOClO2<HOClO3
|
|

pls show the terminals of the capacitor so that i can say if it is in parallel or in series

but how are halogens more stable in higher oxidation states when they are so electronegative
|
|
|
|
when u draw resonance structures for phenol u will get negative charge on ortho and para positions. no2 being a electron withdrawing group stabalises the negative charge and hence makes it more acidic and as the negative charge doesnt come on meta position presence of NO2 in meta position has no effect..para is more acidic because of symmetry

why are higher oxides of halogens stable??????

what is the product when cyclohexene is chlorinated in presence of light?????

thank aatish i got it cleared now

the resistivity of conductor increases with temp because the atoms gain kinetic energy and start oscillating which obstructs the flow of current but in a semiconductor the energy due to increase in temp breaks the bond and hence provides more electron for conduction

the potential diffrenc is directly propotional to resistance..hence tha potential drop acroos the 12 ohm resistor is greater therefore the potential at B is less than at A hence the current flows from A to B......
BY the way it is a wheatstone bridge but it is not balanced

cr has stable configuration because of half filled orbitals
