1 Briefly explain why the amine shown below can only be isolated as a racemic mixture of the R-and S-enantiomers while the ammonium bromide exists only as the S-enantiomer 9) What would be the decreasing order of reactivity of the following carbonyl compounds towards nucleophilic reagents? (most reactive to least reactive) CH3 0% iv i>ii >iii >iv i >ii > ii >iv iv > ii >i> ii h) Which compound of formula CsH,N is expected to have the lowest boiling point? 9% i) Which of the sulfonamides would be soluble in aqueous KOH solution? O. O S. CH3 CH3 CH3 ) Which compound is a hemi-acetal? O OH
