(b) Each of the following alcohols has been subjected to acid-catalyzed dehydration and yieldsa mixture of alkenes. Determine Zaitsev or Hoffman rule is applied and identify the majorand minor products. Explain your answers

Draw the products resulting from addition of a Grignard reagent to an aldehyde. Use a dash or wedge bond to indicate the stereochemistry of substituents on asymmetric centers, where applicableIgnore any inorganic byproducts. 1) PhMgCl (C6H5MgCl) 2) HCI / H₂O

(c) Treatment of 4-tert-butylcyclohexanone with the unusual reducing agent magnesium hydride leads to the cyclohexanols 1 and 2 as shown below. Answer ALL parts (i) to (iii). НО.,,, 1. MgH₂, THF 2. HCI, H₂O + но, 2 minor product major product (i) Draw the lowest energy chair conformation of each of alcohols 1 and 2. (ii) Hence, explain which of the two compounds is lower in energy. (iii) As shown, isomer 2 is the major product. Explain how this result allows you to decide whether the reaction is under kinetic or thermodynamic control.
