Question

Two isomeric compounds A and B have the formula C 3 H 6 Cl 2 . With aq. KOH solution A gives propionaldehyde and B gives acetone. Then A and B respectively are (A) CH 3- CCl 2- CH 3 and CH 3- CH 2- CHCl 2 (B) CH 3- CHCl - CHCl 2 and CH 3- CH 2- CHCl 2 (C) CH 3- CH 2- CHCl 2 and CH 3- CCl 2- CH 3 (D) CH 3- CHCl - CHCl 2 and CH 3- CCl 2- CH 3

Terminal geminal dihalides give aldehydes and that of other geminal dihalides give ketones with aq. KOH. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/fdf87f4959becc2be7eedd8a674b7906-.png" />

Q. Two isomeric compounds $A$ and $B$ have the formula $C_{3} H_{6} C l_{2} .$ With aq. $K O H$ solution $A$ gives propionaldehyde and $B$ gives acetone. Then $A$ and $B$ respectively are

$C H_{3} - CC l_{2} - C H_{3}$ and $C H_{3} - C H_{2} - C H C l_{2}$

$C H_{3} - C H Cl - C H C l_{2}$ and $C H_{3} - C H_{2} - C H C l_{2}$

$C H_{3} - C H_{2} - C H C l_{2}$ and $C H_{3} - CC l_{2} - C H_{3}$

$C H_{3} - C H Cl - C H C l_{2}$ and $C H_{3} - CC l_{2} - C H_{3}$

Terminal geminal dihalides give aldehydes and that of other geminal dihalides give ketones with aq. $K O H$ .

Q. Two isomeric compounds A and B have the formula C3​H6​Cl2​. With aq. KOH solution A gives propionaldehyde and B gives acetone. Then A and B respectively are

CH3​−CCl2​−CH3​ and CH3​−CH2​−CHCl2​

CH3​−CHCl−CHCl2​ and CH3​−CH2​−CHCl2​

CH3​−CH2​−CHCl2​ and CH3​−CCl2​−CH3​

CH3​−CHCl−CHCl2​ and CH3​−CCl2​−CH3​
