In the reaction of 1-chloropentane and potassium tert-butoxide, the dominant mechanism is A) SN1. B) SN2. C) E1. D) E2. Reaction of 2-chloro-2-methoylpentane with methanol leads to three products. Which of the following products is NOT obtained from this reaction? A) 2-Methyl-2-pentanol B) 2-Methoxy-2-methylpentane C) 2-Methyl-1-pentene D) 2-Methyl-2-pentene What is the major product obtained by reaction of reaction of (R)-2-bromohexane with sodium acetate in dimethylformamide? A) 1-Hexene B) 2-Hexene (cis and trans) C) dl-2-Acetoxyhexane D) (S) - 2- Acetoxyhexane Consider the following two anionic molecules. Which of the following statements is TRUE? A) I is more basic and more nucleophilic than II. B) I is less basic and less nucleophilic than II. C) I is more basic but less nucleophilic than II. D) I is less basic but more nucleophilic then II Consider ammonia (l) and water(ii) which of the following statements is TRUE? A) I is more basic and more nucleophilic than II. B) I is less basic and less nucleophilic than II. C) I is more basic but less nucleophilic than II. D) I is less basic but more nucleophilic than II. Which halide ion is the best nucleophilic than II. Which halide ion is the best nucleophile in dimethyl sulfoxide solution? A) fluoride B) chloride C) bromide D) iodide Which reagent is a good nucleophile? A) NH_3 B) HBr C) Br_2 D) BH_3Explanation / Answer
Answer 9. The reaction proceed by E2 Mechanism beacuse the base is strong and bulky in nature which give 1-pentene.
