Explain the
`(CH_3)_3 C^(-)` is less stable than `bar(C) H_3`.

Explain why (CH_(3))_(3)overset(+)C is more stable than CH_(3)overset(+)CH_(2) and CH_(3) is the least stable cation

Consider the fallowing statement : (I) CH_3OC^(o+)H_2 is more stable that CH_3CH_2^(o+) (II) Me_3C^(o+) is more stable than CH_3CH_2C^(o+)H_2 (III) CH_2=CH-C^(o+)H_2 is more stable than CH_3CH_2C^(o+)H_2 (IV) CH_2=C^(o+)H is more stable thn CH_3C^(o+)H_2 of these statement:

Statement-1: CH_(3)CH_(2)overset(o+)(CH_(2)) is less stable than CH_(3)-underset(H)underset(|)(N)-overset(o+)(CH_(2)) and Statement-2: Carbocation with adjacent hetero-atom like N O are less stable .

The carbocation CH_(3)overset(+)(C)HCH_(3) is less stable than

Assertion: (C_(2)H_(5))_(3)N is less basic than trimethylamine (CH_(3))_(3)N Reason: Due to hyperconjugation of C_(2)H_(5) is less than methyl.

CH_(3)COO^(-) ion is more stable than C_(2)H_(5)O^(-) ion. Assign reason.

Assertion : HC-=C^(-) is more stable than H_(2)C=CH^(-) . Reason : HC-=C^(-) has more s-character than H_(2)C=CH^(-) .

Explain the following : (a) Why MeNH overset (oplus) CH_2 (I) is more stable more than MeCH_2 overset (oplus) CH_2 (II) when both are 1^@ carbocations ? (b) Which of the following intermediate is unstable ? ( c) Why allylic free radical (CH_2 - CH = CH_2) (I) is more stable than propy1 free radical (dot C H_2 - CH_2 - CH_3) (II) , when both are 1^@ free radicals ?

A : C_(2)H_(5) -""^(+)CH —C_(2)H_(5) . is more stable than CH_(3)-""^(+)CH-CH_(3) R : Positive inductive effect of C_(2)H_(5) group is less than CH_(3) —group.
