(a)
Interpretation: The number of stereogenic centers present in the product is to be determined.
Concept introduction: A carbon atom which is bonded to four different groups is termed as chiral center or stereogenic center. The groups around the stereogenic center are prioritized on the basis of

- Which of the following compounds undergo Friedel–Crafts alkylation with CH3Cl and AlCl3? Draw the products formed when a reaction occurs.arrow_forward5. Butylated hydroxy toluene (BHT) is an anti-oxidant added to many food products (e.g. breakfast cereals) to increase their shelf-life. BHT is synthesized from p-cresol by reaction with 2-methylpropene in the presence of phosphoric acid. a) What is the structure of BHT ? b) Account for the regioselectivity of tert-butyl group substitution in the synthesis of BHT. c) Propose a mechanism to explain the formation of the electrophile in the synthesis of BHT.arrow_forwardSynthesize each compound from cyclohexanone and organic halides having s4 C's.
