Question

Just need help with number #7. Im confused whether its an enantiomers or diastereomers

PS2 →h me molecular 'to, mula CeHu? Br Br a) Same b enantiomers d) fonstitutional isomers c) diastereomers 7) Are the two molecules below : the same, enantiomers, diastereomers, cons CH3 constitutional isomers? H3C CH2CH3 CH2CH3 a) Same b) enantiomers di constitutional isomers ) diastoreomers 8) If a mixture of two enantiomers enantiomeric excess? contains 65% of the R enantiomer and 35% of the S enantiomer, what is the a) 65% b)35%/c) c) 15% p. are molecules which contain chiraltt centers and a plane of symmetry Racemates b) diastereomers 9) a) d)optically active compounds c) meso compounds polarized light +45e while the s xture containing both enantiomers rotates plane 10) The R enantiomer of a pair of chiral molecules rotates plane a) b) c) d) enantiomer rotates plane polarized light 45°.
