Short Answer TypeExplain the reason for the following:
A primary alkylhalide, RX, reacts with KCN to give an alkyl cyanide and with AgCN to give an alkyl isocyanide as the major, product.
KCN is ionic in nature so it dissociates completely into K+ and CN- also, C-C bond is more stronger then C-N bond because of this when haloalkanes react with KCN to form alkyl cyanides.
AgCN is convalent in nature thus, it does not dissociate in to Ag+ and CN- and on nitrogen electron density is high thus haloalkane react with AgCN and isocyanide is form.
Explain the reason for the following:
Tertiary butyl iodide forms tertiary butyl alcohol with water, but with an alkali solution, it yields isobutylene (2-methyl propene).
Explain the reason for the following:
Unlike the chlorine atom in CH3Cl, that in chlorobenzene, C6H5Cl is not easily replaced by the -OH group.
Explain the reason for the following:
Halogens delocalize electrons in the benzene ring in the order F > Cl > Br > I.
