JEE Main 2020 (4 Sep, Shift 1) Chemistry Q39: An organic…

Question

An organic compound (A) (molecular formula $\mathrm{C_6H_{12}O_2}$) was hydrolysed with dil. $\mathrm{H_2SO_4}$ to give a carboxylic acid (B) and an alcohol (C). 'C' gives white turbidity immediately when treated with anhydrous $\mathrm{ZnCl_2}$ and conc. HCl. The organic compound (A) is :

Accepted Answer

Option 1: [figure: line structure: a line from the lower left to a carbon that has a double bond to O drawn above it and a single bond to an O at lower right; that O is bonded to a carbon from which three further single lines go out (one up, one down, one to the lower right)]

Answer

[figure: line structure: a line from the lower left to a carbon that has a double bond to O drawn above it and a single bond to an O at lower right; that O is bonded to a carbon from which three further single lines go out (one up, one down, one to the lower right)]

Answer

[figure: line structure: a line from the lower left to a carbon that has a double bond to O drawn above it and a single bond to an O at lower right; that O is bonded to a carbon which has one line going up and a chain going down-right then up-right (a two-segment zigzag)]

Answer

[figure: line structure: a line from the lower left to a carbon that has a double bond to O drawn above it and a single bond to an O at lower right; that O is bonded to a vertex with one line going up-right, which leads to a vertex with two further lines, one going up-right and one going straight down]

Answer

[figure: line structure: a two-segment zigzag from the lower left to a carbon that has a double bond to O drawn above it and a single bond to an O at lower right; that O is bonded to a three-segment zigzag going to the right]
