Question

Be sure to answer all parts. Draw both the Syl and El products of the following reaction. 7 ОН The Syl product is: edit structure ... The major El product is: edit structure ... The minor El product is: edit structure ...

Answer 1

Here for the first part, you have skipped the ether formation which lead to wrong product. So i will go with mechanism only for SN1 reaction to make the concept clear.
OH (2-chloro-2 methylpentans + ethanol ) Here, upon sNI reaction, the reaction will proceed in a stens vid an intermedinte formalion'. Let us write the reaction thur chemical name. in terms of LCH3 - CH2 - CH2 - C-CH3 + CH3 - CH2 ~ OH CH3 Here the substrate as a 30 halid and the ethanol is a weak nucleophils as well as a polar protic solvent so the Creaction goes by SNl mechanism. Nb: No suaridgement ruided since carbocation is already 30.

Mechanism I lep - I Love of ci to form a 30 carbocation, which I is more stable CH2-CH-CH₂ - Ć- CH3 I c H ancha-cha-ct ao carlocation Chia s lep 1 Nucleophilic attack by ethanol CHO CH₂ - CH₂ - CH2 - C + CH3 - CH₂-OH a CHg CH, CH3 - CH₂ - CH2-6-0 - CH₂ - CH₂ Sten - Ilon , Deporolonation of onconium con ICH CHA-CH 2 -CH2-c-ot-CH₂-CH3 + CH3 - CH2-OH!

- CH3 CH₂ - CH2 - CH₂ - & -o- CH2 - CH3 - CH₂ - CH2 - OH2 + Hence the major by sol reaction of product we obtain following compound is on elimination reaction, the govern compound looses & chloring ton! chlown as well as hydrogen atom from the Rugblouring resletion The major product is determined by Saytzelf rubl which says that the proffered I wroduct obtained on dehydrohalogination. in the alkens which has the greater number of alkyl groups attached to I double bonded carbon alom.

Hope you understand the answers. Thanks
