Question

32 C) 64 D) 128 Which statement about enantiomers is false? A) enantiomers have the same boiling and melting points. B) enantiomers have the same chemical properties in an achiral environment. C) enantiomers have the same atom connectivity. D) enantiomers have the same three dimensional orientation Which statements about stereoisomers are true? I) enantiomers and diastereomers have the same physical proper II) 50/50 mixtures of R and S enantiomers are called racemic m III) meso isomers rotate the plane of plane polarized light. IV) dextrorotatory compounds rotate plane polarized light to th

Explanation / Answer

a)

not likely, since locaiton of polar gorups will affect this interaction

b)

false, by definition, they are chiral, then, achiral environemnt wont fit here

c)

true, they have the same atom conectivity

d)

false, they will have different location groups

Q2.

i)

Not really, enentiomers can have a single chiral carbon, whereas diastereomers require at least 2 chiral centers

ii)

correct, if R/S is 50-50% then this is racemic

iii)

not really, since they are not sensitive

iv)

D compounds will roate to the right

Choose II and IV if possible, this appears to be "C"
