    Predict the specific rotation of mixture of 30%(-)-2-bromobutane and 7...
    To predict the specific rotation of a mixture, we need to know the specific rotations of each enantiomer and the percentage composition of the mixture.

    Given that the mixture contains 30% (-)-2-bromobutane and 70% (+)-2-bromobutane (enantiomer), we can assign specific rotations to each enantiomer.

    Assuming that (-)-2-bromobutane has a specific rotation of -10 degrees (hypothetical value) and (+)-2-bromobutane has a specific rotation of +10 degrees (hypothetical value), we can calculate the specific rotation of the mixture.

    Specific rotation of mixture = (Specific rotation of (-)-2-bromobutane) x (Percentage of (-)-2-bromobutane) + (Specific rotation of (+)-2-bromobutane) x (Percentage of (+)-2-bromobutane)

    Specific rotation of mixture = (-10 degrees) x (0.30) + (+10 degrees) x (0.70)

    Specific rotation of mixture = -3 degrees + 7 degrees

    Specific rotation of mixture = +4 degrees

    Therefore, the specific rotation of the mixture of 30%(-)-2-bromobutane and 70%(+)-2-bromobutane enantiomer is +4 degrees.
