Answer: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 .
The unit measurement of the rate constant is a guide to tell you the rate order. If it's unit is 1/time, then it is a first-order reaction. From the picture attached, the formula to be used would be:
ln[A] = ln[A₀] - kt ln[0.21] = ln[A₀] - (1.37)(1.2) Solving for A₀, A₀= 1.09 M
<em>Hence, the original concentration of X was 1.09 M.</em>
