Question

The most stable carbonium ion among these is: (A) C 6 H 5- CH 2 overset+CH 2 (B) CH 3 overset+CH 2 (C) ( C 6 H 5)3- overset+C (D) C 6 H 5 overset+ C H 2

Due to more possibility for delocalisation of ( C 6 H 5)2- overset +C - C 6 H 5 because of presence of π- electrons in conjugation, ( C 6 H 5)2- overset + C - C 6 H 5 is the most stable ion.

Q. The most stable carbonium ion among these is:

$C_{6} H_{5} - C H_{2} C + H_{2}$

$C H_{3} C + H_{2}$

$(C_{6} H_{5})_{3} - C +$

$C_{6} H_{5} C + H_{2}$

Due to more possibility for delocalisation of $(C_{6} H_{5})_{2} - C + - C_{6} H_{5}$ because of presence of $π -$ electrons in conjugation, $(C_{6} H_{5})_{2} - C + - C_{6} H_{5}$ is the most stable ion.

Q. The most stable carbonium ion among these is:

C6​H5​−CH2​C+H2​

CH3​C+H2​

(C6​H5​)3​−C+

C6​H5​C+H2​

Due to more possibility for delocalisation of (C6​H5​)2​−C+−C6​H5​ because of presence of π− electrons in conjugation, (C6​H5​)2​−C+−C6​H5​ is the most stable ion.

$C_{6} H_{5} - C H_{2} C + H_{2}$

$C H_{3} C + H_{2}$

$(C_{6} H_{5})_{3} - C +$

$C_{6} H_{5} C + H_{2}$

Due to more possibility for delocalisation of $(C_{6} H_{5})_{2} - C + - C_{6} H_{5}$ because of presence of $π -$ electrons in conjugation, $(C_{6} H_{5})_{2} - C + - C_{6} H_{5}$ is the most stable ion.
