B) (5)-2-pentanol C) racemic pentanol D) 1-pentanol E) 3-pentandl 14 What is the prodact of the Sy2 reaction of (R)-2-bromopentane with sodium methoxide? A) B) E) (R)-2-pentanol 15. Name the product of the following SN2 reaction: OH CHCH CH: A) (S)-2-bexanol B) (R)-2-hexanol C) (5)-3-hexanol D) (R)-3-hexanol 16. Which of the following is a secondary alkyl halide? A) CH3Br B) (CH3)3CBr C) (CH3)2CHBr D)(CH3)2CHCH2Br 17, Which of the following is not a nucleophile?

Explanation / Answer

12)

rate depends on concentration of both reactants since this is SN2 reaction

Rate law is:

rate = k [CH3Br][OH-]

doubling both concentration will make rate 4 times

Answer: D

13)

in SN2 reaction, inversion takes place

So, product will be S
