What is the final product of following reaction ?
Isopropyl alcohol `overset((i)SOCl_2)underset((ii)Mg//"ether")to` ?
(iii) `CH_3-CHO`
(iv) `H_3O^+`
(v) `K_2Cr_2O_7//H^+`

Options

A. `CH_(3)-CH_(2)-overset(O)overset(||)C-CH_(2)-CH_(3)`
B. `CH_(3)-underset(CH_(3))underset("| ")"CH"-overset(O)overset(||)C-CH_(3)`
C. `CH_(3)-underset(CH_(3))underset("| ")"CH"-CH_(2)-COOH`
D. `CH_(3)-overset(O)overset(||)C-CH_(2)-overset(CH_(3))overset("| ")"CH"-CH_(3)`

Answer

B

Explanation

`CH_(3)-overset(OH)overset(" |")"CH"-CH_(3)overset(SOCl_(2))rarr CH_(3)-overset(Cl)overset(|)CH-CH_(3)overset(Mg)rarrCH_(3)-overset(MgCl)overset("| ")"CH"-CH_(3)`
`underset("2. "H_(3)O^(+))overset("1. "CH_(3)-overset(O)overset(||)C-H)rarr CH_(3)-underset(CH_(3))underset(" |")"CH"-overset(OH)overset("| ")"CH"-CH_(3)overset(K_(2)Cr_(2)O_(7))rarr CH_(3)-underset(CH_(3))underset(" |")"CH"-overset(O)overset(||)C-CH_(3)`
