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 (Q) isA. `CH_(3)-overset(CH_(3))overset(|)(C)=CH_(3)`B. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=CH-CH_(3)`C. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(2)-CH=CH_(2)`D. `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH=CH_(2)`

Answer» Correct Answer - D
`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`
