1) Which of the following alcohols will react most rapidly with the Lucas reagent (HCl, ZnCl2)?
A) (CH3)3COH
B) CH3CH2CH2CH2OH C) CH3CHOHCH2CH3 D) (CH3)2CHCH2OH
The answer is A but can someone explain how A is tertiary? Can me tell without drawing out the structure?
Alcohol order of reactivity: 3° > 2° > 1°
2) When 1-pentanol is heated with HCl/ZnCl2, 1-chloropentane is the major organic
product. This reaction proceeds through an ________ mechanism, and ________ is produced as a byproduct.
A) SN1, H2O
B) SN2, H2O C) SN1, H2 D) SN2, H2 E) E2, H2
1° alcohols follow SN2. 2°/3° follow SN1
the answer is B but can you explain why?
