OH Он A) B) C) D) E) но но HO, он 12.) The molecule with the most chiral carbon atoms from the drawings above has how many chiral carbon atoms? A) 0 В) 1 C) 2 D) 3 E) 4 F) cannot be determined from the drawings

Please answer 1,2,3

CI 0 CH3CH=CHCHCH3 4-chloro-2-pentene Four stereoisomers exist for 4-chloro-2-pentene. Draw the structure of the isomer that has the E configuration around the double bond and the R configuration at the chiral center. Use the wedge/hash bond tools to indicate stereochemistry where it exists. • You do not have to explicitly draw H atoms. • If a group is achiral, do not use wedged or hashed bonds on it. Jn (1²
