Which of the following reactions yield an alcohol as the major organic product? select all that apply.
a. reaction of a ketone with h2 and pd
b. hydrogenation of an alkene
c. hydroboration-oxidation of an alkene
d. oxymercuration-reduction of an alkene

The options A ,C and D would produce alcohols.

Explanation:

The reaction of a ketone with hydrogen gas in presence of palladium as a catalyst is reduction reaction which is used to reduce the ketones  to alcohols.

so option A is correct.

The hydrogenation reaction of alkenes is als0 a reduction reaction in which the double bonds  of the alkene are reduced and the unsaturated alkenes are converted to saturated compound.The hdyrogenation of alkenes do not produce any alkenes they just produce alkanes.

So option B is incorrect

The hydroboration-oxidation of alkene is one of the prominent methods to oxidize alkenes to alcohols so this reaction would lead to the formation of alcohols.It follows anti-markowinkoff rule.

so option C is correct.

The oxymercuration reaction is also a reaction of alkenes through which alkenes can be converted to alcohols .

increased stability in the completion of fluorine's outer shell.

i think   the answer is c hope i'm right
