Vedclass · Answer

(A) The reaction is the $OXO$ process or hydroformylation of alkenes.In this reaction,an alkene reacts with $CO$ and $H_2$ in the presence of a rhodium $(Rh)$ or cobalt catalyst to form an aldehyde.For the substrate $CH_3CH_2CH=CH_2$ (but$-1-$ene),the hydroformylation leads to two isomeric aldehydes:$1$. $CH_3CH_2CH_2CH_2CHO$ (pentanal,linear product)$2$. $CH_3CH_2CH(CH_3)CHO$ ($2$-methylbutanal,branched product)Using a rhodium catalyst,the linear aldehyde is typically the major product due to less steric hindrance during the formation of the transition state.Therefore,the major product is $CH_3CH_2CH_2CH_2CHO$.

The major product of the following reaction is:
$CH_3CH_2CH=CH_2$ $\xrightarrow[Rh \ \text{catalyst}]{H_2/CO}$
