`H_(3)C-underset(O)underset(||)(C)-CH_(2)-CH_(3)+CH_(3)MGBR`
`CH_(3)-overset(CH_(3))overset(|)(CH)-CH_(2)-CH=O+CH_(3)MgBr`
`CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(2)-COCl+MgCl`
`CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=CH_(2)`

Solution :`P=CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(2)-COCl+CH_(3)MgCl`
`,Q= CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=CH_(2) , ""R&S=CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=O,O+CH_(2)=O`
