Question

The product `(B)` obtained in the reaction
`CH_(2) = CH_(2) + CO + H_(2)O underset(100^(@)C,"pressure") overset(Co_(2)(CO)_(s)) rarr A underset(Ni) overset(H_(2))rarr B`
is
A. `CH_(3)CH_(2)CHO`
B. `CH_(3)CH_(2)OH`
C. `CH_(3)CH_(2)CH_(2)OH`
D. `CH_(3)overset(OH)overset(|)(CH)CH_(3)`

Answer 1

Correct Answer - A
It is oxo process followed by reduction. In the presence of octacarbonyldicobalt (catalyst), alkenes react with carbon monoxide, and hydrogen to yield aldehydes.Upon reduction , the aldehydes give primary alcohols.
`CH_(2) = CH_(2) + CO + H_(2)O underset(100^(@)C ,"pressure") overset([Co(CO)_(4)]_(2)) rarr`
`CH_(3)underset((A))(CH_(2))CHO underset(Ni)overset(H_(2))rarr CH_(3)underset((B))(CH_(2)OH)`
