Hyperconjugation describes the orbital interactions between the pi -system and the adjacent sigma -bond of the substituent group(s) in organic compounds. Hyperconjugation is called as Baker and Nathan effect. The necessary and sufficient conditions for the hyperconjugation are: (i) Compound should have at least one sp^(2) -hybrid carbon of either alkene, carbocation or alkyl free radical. (ii) alpha -carbon with respect to sp^(2) -hybrid carbon should have at least one hydrogen. Hyperconjugation are of three types: (i) sigma(C-H),pi -conjugation, (ii) sigma(C-H), positive charge conjugation, (iii) sigma(C-H) , odd electron conjugation. The hyperconjugation may be represented as, Number of resonating structures due to hyperconjugation =(n+1) , where n is the numebr of alpha -hydrogen. Greater is the number of such forms, more is the stability of the species under consideration. Which of the following carbocations will show highest number of hyperconjugative forms?

in an ionic bond the cation tends to polarise the electron cloud of the anion by pulling electron density towards itself This causes development of covalent character in the ionic bond because the electron density gets localised in between the nuclei The tendency of the cation to bring about the polarisation of the anion is expressed as its polasising power The ability of ion to undergo polarisation is called its polarisability The polarising power of a cation or an anion is decided on the basis of F ajans' rules as follows . (i) The smaller the cation, the higher is its polarising power (ii) Cations with pseudo-noble gas configuration (ns^(2)np^(6)nd^(10)) have relatively high polarising power than those with noble gas configuration (ns^(2) np^(6)) (iii) The larger the size of the anion, the higher is its polarisability Choose the correct order of polarisability for the following I^(Θ),Br^(Θ),CI^(Θ)F^(Θ) .
