A 2:3, dl pair mixture (by weight) has an observed specific rotation of 1 6 ∘ . The specific rotation of the optically pure component is (in degrees) ____

ee = 5 1 × 100 = 20% ∴ 20 = α 16 × 100 ⇒ α = 8 0 ∘

A 2:3, dl pair mixture (by weight) has an observed specific rotation of $1 6^{\circ}$ . The specific rotation of the optically pure component is (in degrees) $____$

Answer:

Solution:

$ee = \frac{1}{5} \times 100 = 20%$

$∴ 20 = \frac{16}{α} \times 100 \Rightarrow α = 8 0^{\circ}$
