Question

\[C{H_3}O{C^ + }{H_2}\] is more stable then\[C{H_3}CH_2^ + \]?

Answer 1

Hint: When a carbon element attached with more electronegative element is compared to itself. Then the more electronegative atom having a tendency attracts the shared pairs of electrons toward itself.


Complete step by step answer:When more electronegative elements attract the shared pairs of electrons towered themselves then carbon carries a positive charge and the electronegative atom carries a negative charge. The positive charge carrying carbon is known as carbocation. A carbocation is also called a carbanion.
Is more stable than \[C{H_3}O{C^ + }{H_2}\]then\[C{H_3}CH_2^ + \] due to inductive effect. Alkyl group is an electron-donating group and when donating electrons to oxygen then oxygen having to carry already two lone pairs so it donates the lone pair electrons to that carbon which carries a positive charge. Due to this, the positive charge on carbon disappears and it becomes more stable.
But in \[C{H_3}CH_2^ + \] oxygen atom is not present so this compound is less stable as compared to\[C{H_3}O{C^ + }{H_2}\].

Note: And carbocation are different types on the basis of how many other R groups attached directly to that carbon which carries a positive charge. \[\left( 1 \right)\] When carbocation is directly attached to the one R group and other are different atoms like hydrogen or any other atoms. This is known as primary carbocation.
\[\left( 2 \right)\] When carbocation is directly attached to the two R groups and others are different atoms like hydrogen or any other atoms. This is known as secondary carbocation.
\[\left( 3 \right)\] When carbocation is directly attached to the three R groups and others are different atoms like hydrogen or any other atoms. This is known as tertiary carbocation.
A carbocation is a trigonal planar in shape having a bond angle is \[{120^o}\].
In Carbocation (When carbon carries positive charge) having hybridization is \[s{p^2}\] in which one s and two p orbital intermix each other and to form hybrid orbital (having to carry equal energy).
