Step 1
" Step 2: In organic chemistry, a leaving group is an atom or group of atoms that detaches from a molecule during a chemical reaction. The ability of a group to leave is related to its stability as an anion (or neutral molecule) once it has departed. Step 3: A Show more…

21) For an Sn1 reaction to occur which one of the following is not appropriate to use protic solvent weak nucleophile weak base strong nucleophile Question 22 Which one of the following is the best leaving group? I, because of the large size of the iodine I, because iodine is the least electronegative halogen F, because of the small size of F F, because , Fluorine is the most electronegative halogen

Okay, a final, more tricky one: Which reaction conditions tends to favor SN1 and E1 reactions? a) A weak base and poor nucleophile b) A strong base and strong nucleophile c) A strong base and poor nucleophile d) A weak base and strong nucleophile

Which of the following order/statement (s) is/are correct? (a) In $S_{N} 1$ reactions, $\mathrm{AgNO}_{3}$ increases the rates of solvolysis (b) Soft bases have enhanced nucleophilicities towards $\mathrm{S}_{\mathrm{N}} 2$ reactions. (c) $\mathrm{PhSO}_{3}^{-}>\mathrm{Cl}_{3} \mathrm{CCOO}^{-}>\mathrm{CH}_{3} \mathrm{COO}^{-}>\mathrm{PhO}^{-}$(leav- ing group ability) (d) HCOOH may lead a tertiary halide towards $\mathrm{S}_{\mathrm{N}}^{2} .$
