which on of the following has the highest dipole moment and why ?????

1 CH2Cl2

2 CHCl3

3  CCl4

The first condition is best suited for this conversion               

X^Y + Y^X = 2



YLOGX + XLOGY = LOG2



Y/X + LOGX*DY/DX + X/Y*DY/DX + LOGY = 0



DY/DX ( LOGX + X/Y ) = - ( Y/X + LOGY )



DY/DX { ( YLOGX + X ) /Y } = - { ( Y + XLOGY ) / X }



DY/DX = - Y (Y + XLOGY ) / X ( YLOGX + X )          

Y = X^X



LOGY = XLOGX

1/Y*DY/DX = 1 + LOG X {Taking product rule}



D^2Y/DX^2*I/Y - I/Y^2*(DY/DX)^2 = 1/X



1/Y { D^2Y/DX^2 - 1/Y*(DY/DX)^2 } = 1/X



D^2Y/DX^2 - I/Y (DY/DX)^2 = Y/X



HENCE PROVED

    Kindly suggest sum gud topics for making a chemistry project for the boards practical . suggest a topic which is gud n less time consuming   

i think d 1st one is 2,3,4,5,6-penta cyclopropyl-1 methyl-cyclohexan-1-ol
