Question

Which of the following is more stable ?
CH3CH2^+, Or CH3-CH2-CH2^+​

Answer 1

Answer:

CH3-CH2-CH2^+

Explanation:

POSITIVE INDUCTIVE EFFECT Directly Proptional to stability of compound.

Answer 2

$CH_3-CH_2-CH_2{^+}$ is More Stable

Explanation:

• $CH_3-CH_2-CH_2{^+}$  is more stable than $CH_3-CH_2{^+}$
• The reason is that there are two electron-withdrawing groups present in$CH_3-CH_2-CH_2{^+}$ in comparison to $CH_3-CH_2{^+}$ in which only one withdrawing group is present
• Presence of more electron-withdrawing groups develops a positive inductive effect

       Positive Inductive Effect ∝ Stability of compound

∴ $CH_3-CH_2-CH_2{^+}$ is more stable in comparison to $CH_3-CH_2{^+}$ due to positive inductive effect.
