Question

Which of the given pair of $S_{N}1$ reaction would you expect to proceed faster? Explain your answer.

• A. $3^o$-alcohol > $2^o$-alcohol
• B. $3^o$-alcohol < $2^o$-alcohol
• C. $3^o$-alcohol = $2^o$-alcohol
• D. None of these

Answer 1

The correct option is A $3^o$-alcohol > $2^o$-alcohol

Option A is the correct answer as tertiary alcohol reacts faster than secondary alcohol which in turn reacts faster than primary alcohol towards $S_{N}1$ reaction.
