106Q2. +CH2-CH=CH-O- (maybe)
Q.1) If 3 tan^-^1 [1/(2+\sqrt{3})] - tan^-^1(1/x) = tan^-^1(1/3) , then x equals :
a) 1 b) 2 c)3 d) √3
here , [] doesn't mean greatest integer function.
Q,2) How can polarisation of acrolein be expressed ?
acrolein : CH2=CH - CH=O

1thnx fr confirmation. options were a bit weird. nyway i got it.
plz try the 1st one if possible
106tan-1(1/x+1/31-1/3x) = 3tan-1(1/(2+√3))
=> tan-1(x+33x-1) = 3tan-112+√3
=> (x+3)/(3x-1) =3(2-√3) - (2-√3)31-3(2-√3)2
= 12√3-20-20+12√3
=> (x+3)/(3x-1) = 1
=> x+3 = 3x-1
=> 2x = 4
=> x=2
