Give the major organic product of the following reactions.(a-e) ### Reaction DescriptionsThe image contains a series of chemical reactions labeled from a to e, with specific reagents and conditions indicated for each reaction. Here’s a detailed transcription and explanation of each one:#### a) Reaction- **Reactant:** An aromatic ketone with a methyl group (acetophenone).- **Reagents:** 1. \( \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{MgBr} \) (butylmagnesium bromide, a Grignard reagent) 2. \( \text{H}_3\text{O}^+ \) (acidic workup)- **Explanation:** Involves nucleophilic addition of the butyl Grignard reagent to the carbonyl group, followed by protonation to give an alcohol.#### b) Reaction- **Reactant:** Chlorinated ketone with an isopropyl group.- **Reagents:** \( (\text{CH}_3\text{CH}_2)_2\text{CuLi} \) (diethylcuprate, a Gilman reagent)- **Explanation:** The Gilman reagent substitutes the chlorine with an ethyl group, possibly through a conjugate addition.#### c) Reaction- **Reactant:** Alkyl chloride with a ketone functional group.- **Reagents:** 1. 2 equivalents of \( \text{CH}_3\text{CH}_2\text{MgBr} \) (ethylmagnesium bromide, a Grignard reagent) 2. \( \text{H}_2\text{O} \) (water for protonation)- **Explanation:** Double addition of ethyl groups via Grignard reagent, followed by hydrolysis.#### d) Reaction- **Reactant:** Aromatic ester with a ketone functional group.- **Reagents:** 1. \( \text{NaBH}_4 \) (sodium borohydride, a reducing agent) 2. \( \text{H}_2\text{O} \) (water for acidic workup)- **Explanation:** Reduction of the ketone to an alcohol.#### e) Reaction- **Reactant:** Alkylmagnesium bromide (GRignard reagent).- **Reagents:**
