Draw the structure of the major product(s). If there is no reaction write no reaction If the starting material is chiral then assume it is optically pure unless otherwise indicated. Show stereochemistry clearly for all chiral products. For products that exist as a racemic mixture, give only one of the enantiomers. If the products are formed as mixture of diastereomers then give the structures for each diastereomer. If the major product or product mixture will rotate the plane of polarized light, please make that clear. Please answer all 3 parts, will upvote
