Question

6. For each of the molecules below (A-D), determine whether the molecule is chiral, achiral, meso, or none. Be as specific as possible. (4 pts) CH3 CH3 CH3 CH2CH3 Bry CH₃ наслесна | HCBr CH2CH3 CH3 CH3 AB H3 CH3 HO CHARY 7. Consider isomers that contain a cyclopropane ring and have the molecular formula C5H10. (10 pts) a. Draw three (3) structures that would be included in this class of isomers and are achiral. Note: points will be deducted for redundant or irrelevant structures. (6 pts) b. Draw two (2) structures that would be included in this class and are chiral. Note: points will be deducted for redundant or irrelevant structures. (4 pts)

Answer 1

Lans-6 CH3 93 43 It is achiral molecule Due to centre of symmetry and Otis meso compound because it have 2 Chiral Centre and centre of symm. In Compound (B) one Chiral centre is present so molecule ys Chiral.

Due to plane It is achiral molecule of symmetry. @ CH₂ CH3 Риз- e Br It is achiral molecule Due to plane of symmetryt is also meso Com pound os Ans. 7 Cshio Isomer of cyclopropane
