Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

1. Deduce the structure of each compound from the information given. All unknowns in this problem have molecular formula C8H12. (a) Upon catalytic hydrogenation, unknown W gives cyclooctane. Ozonolysis of W, followed by reduction with dimethylsulfide, gives octanedioic acid, HOOC—(CH2)6—COOH. Draw the structure of W. (b) Upon catalytic hydrogenation, unknown X gives cyclooctane. Ozonolysis of X, followed by reduction with dimethyl sulfide, gives two equivalents of butanedial, O=CH—CH2CH2—CH=O. Draw the structure of X.

A compound X of molecular formula C7H14 when hydrogenated produces 2,4-dimethylpentane and when hydroborated the obtained alcohol is 2,4-dimethyl-1-pentanol. a. What is the structure of X? b. If X is reacted with H2O catalyzed by H2SO4, what product is obtained? Write the structure, give the name, and write the complete mechanism, step by step of this reaction, in such a way as to explain the formation of the compound (DO NOT FORGET THE CORRECT USE OF ARROWS!).
