P is an alcohol which on heating with ` Al_(2)O_(3)_(3)` forms an alkene Q. Q on ozonolysis produces R and S. when the mixture of R and S is heated with conc. `NaOH`, redox reaction takes place and a mixture of an acid salt and alcohol is formed. The compound R and S areA. `CH_(3)-overset(CH_(3))overset(|)(C)=O,CH_(2)=O`B. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)=CH=O,CH_(3)CH=O`C. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=O +CH_(2)=O`D. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=O +CH_(2)=O`

Answer» Correct Answer - C
`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`
