Anhydrous ZnCl2 in Lucas reaction is not used to absorb water, rather, the Zn, is used to form complex with the OH- , so that it becomes a good leaving group.
We already know that OH- is not a good... link 9 years, 4 months ago
let the length of the rod be l..
i am not so sure better check with a text or guide..
let the x co-ordinate be a
let y co-ordinate be b
then a^2 + b^2 = l^2
as the angle is 60
and... link 9 years, 3 months ago
having highest ionisation enthalpy it gives away electron very easily, hence can get oxidised very easily, and by donating electron to others so easily, it can act as reducing agent.

Standard Free Energy Difference = Useful work = PdV
dV = m/(1/2.25 - 1/3.31) 10^-3 cubic metre
Therefore, 1895 = P * m/(1/2.25 - 1/3.31)*10^-3 [where m= mass of the carbon, unfortunately thats not... link 9 years, 4 months ago
Try and understand it this way:
We know that,
resultant amplitude of two interfereing waves:
(A)^2 = (A1)^2 + (A2)^2 + 2 (A1)(A2) (cos φ)
where cosφ = phase difference between the waves

Mutarotation is the change in the optical rotation that occurs by epimerization (that is the change in the equilibrium between two epimers, when the corresponding stereocenters interconvert). Cyclic... link 9 years, 4 months ago
