An ion catalysed polymerization occurs in case of vinyl monomers with electron with drawing groups greater the stability of the carbane ion intermediate more facile is the an ionic polymerization
Which of the following vinyl substituted group more stabilizes the carbaneion ?

A

`-NO_(2)`

B

`-CH_(3)`

C

`-overset(O)overset(||)(C)-H`

D

`C_(2)H_(5)-`

Text Solution

Verified by Experts

The correct Answer is:
C
`CHCl_(3)underset(SbF_(3))overset(HF)rarr CHClF_(2)overset(800^(@)C)rarr CF_(2) = CF_(2) overset("polymerisation")rarr (CF_(2)-CF_(2))_(n)` Teflon
`-overset(O)overset(||)(C)-H` (Aldehyde)

The stability of complex ion depend upon charge, size electronegativity of metal ion. Greater the charge of metal ion greater would be the stability. As size of metal ion decreases stability of metal ion increases complex ion more stable if chelating ligand present. Which increases stability of complex ion

The products of bond breaking, shown below, are not stable, and cannot be isolated for prolonged study. Such species are referred to as reactive intermediate, and are belived to be transient intermediates in many reactions. The general structures and names of four such intermediates are, Charged Intermediates Uncharged Intermediates Carbocations (called carbonium ions in the older literature) are electrophiles and carbananions are nucleophiles. Carbenes have only a valence shell sextet of electrons and are therefore electron deficient. In this sense they are elecrophiles, but the non-bonding electron pair also gives carbenes nucleophilic character. As a rule, the electrophilic character dominates carbene reactivity. Carbon radicals have only seven valence electrons, and may be considered electron deficient, however, they do not in general bond to nucleophilic electron pair, so their chemistry exhibits differences from that of conventional electrophiles. Radical intermediates are often called free radicals. Intermediates are in general stabilised with conjugation, electron donating and electron with drawing groups. Which of the following carbo cations is more stable?

Hyperconjugation describes the orbital interactions between the p-systems and the adjacent s-bond of the substituent group(s) in organic compounds. Hyperconjugation is also called as Baker and Nathen effect. The necessary and sufficient condition for the hyperconjugation are : i) Compound should have at least on sp2 hybrid carbon of either alkene, carbocation or alkyl free radical. ii) A-carbon with respect to sp2 hybrid carbon should have at least one hydrogen. Hyperconjugation are of three types: (i) s(C-H), p-conjugation. (iii) s(C-H), positive charge conjugation iv) s(C-H), odd electron conjugation The hyperconjugation may be represented as Number of resonating structures due to hyperconjugation = (n + 1) where n is the number of a-hydrogen. Greater is the number of such forms, more is the stability of the species under considersation. Which of the following carbocations will show highest number of Hyperconjugation forms?
