Question

32. Which of the following substitution products will form in the reaction below? 1ОН MeOH Но ? -O d. e. A&D C&B a. b. c. All of the above. A&B D
thank you so much!

Answer 1

CH3 Inrich # 30 carbon grom The leaving group te -ch is residing on the tertiary (30) centre. So, The reaction will be SNI because & 30 carbon cen the will will not give SN² battagay product because the incoming nucleophile alill face Stebic hindennce with the substrat. so, The heaction will be-snl. Mechanism: O steb- 1 a ed (Rate deter- (sp3 hybridised -mining step) (B) As the intermidiate (B) is sp²-hybridised so, It is planan and because of bhanahity of the molecule the Nucleophile can approach both from the top face and below face. 8p²-hybridines (Planan) CH3 CH3CH (step-II) CH3- Hell) CH₂-OH u CH3 a (top face attack of CH₃OH) (step-III) CH₃-9 LUNCH
as
CH3 lo a Trillo- CH2 (step-II) bottom face attack of the Nucleophile CH3OH (step-tty CH3 | VtLC-CH, so, the So, product is given, do A and D formed (A) and (0) is the connect option. In a POH () and w ower is the Nucleophile which cuill attack in the steb-dlin 8H chich is not give in the question as nucleophile is me oh! so, (B) and (C) chill not form.
