Acetal is formed by: a) hydration of aldehyde c) reaction of alcohol and aldehyde b) aldol condensation d) dehydration of acetic acid e) none 9. Carbon is found in the highest oxidation state in which of these classes of organic compounds? (A) carboxylic acids (B) alcohols (C) aldehydes (D) alkynes 10. The aldehyde group is acetaldehyde A: can donate a hydrogen to H-bond B: produces a ketone when oxidized C: can form a ketal with an alcohol D: is susceptible to oxidation

Explanation / Answer

Q1

hydrogenaton of this will increase CHO grou pinto COOH group

therefore, this becomes an alcohol group

total carbon chain --> 4 carbons, therefore, butnaol

1 butanol --> since OH gorup is much more important

choose C

Q2

R-CHO --> this is considered an aldehyde,C=O and C-H at the same time
