could someone explain why these are wrong?

A. For the following atachmsents, which would have the highest priority in the Cahn-Ingold-Prelog rules: (a) CCH (ab) COOH, (c) NH2 or (d) NO2 B. Which of the following cyeloalkanes has the highest (best) aqueons solubility: (a) cyclobatane, (b) cyclopentane, or (e) cyclohexane C. Which of the following cormpounds contains a non-carbon chiral center: (a) (b) (c) D. Compound A has a specific rotation of -16.0 . If the observed rotation for a 400 , mg sample of Compound B dissolved in 6.0mL of acetone is recorded at +16.0 , what is the likely composition of the solution: (a) diastereomer of Compound A,(b) enantiomer of Compound A, or (c) racemic mixture 5.
