The optical rotation of the `alpha`-form of a pyranose is `+150.7^(@)`, that of the `beta`-form is `+52.8^(@)`. In solution an equilibrium mixture of these anomers has an optical rotation of `+80.2^(@)`. The precentage of the `alpha`-form in equilibrium mixture is :A. `28%`B. `32%`C. `68%`D. `72%` |

Answer» Correct Answer - A `150.7 (X) + 52.8 (1-X) = +80.2` `150.7X + 52.8X = +80.2` `97.9X = 27.4` `X = 0.279 = 0.28` |
