Options

A. Propanal and propyl magnesium bromide
B. 3-methylbutanal and 2-methyl magnesium iodide
C. 2-dimethylpropanone and methyl magnesium iodide
D. 2-methylpropanal and ispropyl magnesium iodide

Answer

D

Explanation

`underset("2-Methylprpanal")(CH_(3) - underset(CH_(3))underset(|)(CH)-overset(H)overset(|)(C) = O) + underset("Isopropyl magnesium iodide")((CH_(3))_(2) CHMgl rarr)`
`(CH_(3))_(2)CH - underset(CH_(3))underset(|)overset(H)overset(|)(C)-OMgl overset(H_(2)O)(rarr) underset("2, 4-Dimethylpenton-3-ol")((CH_(3))_(2)CH-underset(CH(CH_(3))_(2))underset(|)overset(H)overset(|)(C) - OH)`
