Draw the alkene that would react with the reagent given to account for the product formed. ? + HCI CH3 CH3CCH3 CI • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. #[ ] در ChemDoodle

a) Draw the major product(s) of the following reactions. i) ii) OSO4 NaHSO4, H₂O BH3-THF H₂O₂, NaOH b) Methylcyclohexene reacts with chlorine both in CCl4 and water. i) Draw the structural formula for both the products. > ( )

Answer both

TReview TOpics] [References Draw a structural formula for the major product of the reaction shown. CH3 CH3CHCH=CH2 Show product steréochemistry IF the reactant alkene has both carbons of the double bond within a • Do not show stereochemistry in other cases. If the reaction produces a racemic mixture, just draw one stereoisomer. C P opy aste C.
