Question

Bartleem is a chiral molecule. At 70 ^oC Bartleem is a liquid with a density of 0.722 g/mL. At this temperature and using a 589 nm light source with a 1 dm path length the rotation of light is found to be 71^o. What is the optical rotation for Bartleem?

Expert Solution

Step 1

The formula for the optical rotation is,

$= > {[α]}^{T}_{D} = \frac{{[α]}_{o b s e r v e d}}{c * l}$

where [α ]^T_D = specific optical rotation

[α]_observed = optical rotation observed = 71^o

c = concentration in g/mL = 0.722 g/mL

And l = path length in dm = 1 dm
