Question

s) (2) Wh hich one of the following compounds is expected to react slower by way of an Sy2 mechanistic pathway? wort better Bromomethane b. Bromoethane c. 2-bromopropane d. 2-bromo-2-methylpropane morr carbon tne So 9) Ci Waich ons of oc olowing compound s espcted io res r by y of me pathway? a. Bromomethane b. Bromoethane c. 2-bromopropane d-2-bromo-2-methyl propane 10) (5) Which of the following reactions do you think will occur faster by way of an Sx2mechanistic pathway? Explain your answer below. Fastest H3C OC Br: Hlli H3C CH3 a. CH3 H3C CH3 b. CH3 H3C CH3

Explanation / Answer

A:- Reactivity order for alkyl halides in Sn1 reaction is fallows,

1^o alkyl halides < 2^o alkyl halides < 3^o alkyl halides => So 3^o alkyl halides more faster participate in Sn1 reactions than other alkyl halides.

Reactivity order for alkyl halides in Sn2 reaction is fallows,

1^o alkyl halides > 2^o alkyl halides > 3^o alkyl halides => So 1^o alkyl halides more faster participate in Sn2 reactions than other alkyl halides.

In case of halogen atoms

R-Br is more reactive than R-Cl for both Sn1 and Sn2 reactions.
