Question

OH inctional group as an alcohol, ether, acetal, or 16.72 Label each functional group as an hemiacetal. осна OCH OCH CH2CH3 ОН b. CH3-C-OCH,CH,CH3 CHE 16.73 What acetal is formed when each aldehyde or ketone is

Answer 1

Hemiacetal : i f ether and same carbon group known alcohol on and acetal as nemi acetal exr R -6-OR OH same Hemi ketal: ether and carbon and called as alcohol on ketal group Hemi ketal. R-ç Hence. (b) o ether . ÓH & alcohol 애 ir Hemi ketal . i .CH3C OCH₂ CH₂ CH₂ CH3

-OH y alcohol and -o- is either where group carbon Acetal:- When then two known ethers as . on Acetal same group R & OR ether (OR ether Solution zether (a) : OCH3 . 2CH3 Since Here is R-O-R group which is ether group ether

(6) CH3 LOH - Alcohol - FOT CH₂ CH₂ CH3 CH₂ Yether alcohol and ether are on hence it is Hemi ketal. same 1 Since carbon (C.) ether TOFCH₂ CH₂ CH₃ Since two c hence ether ethers group acetal on same group.

079 ether ether group Two ether Acetal . on same c hence
