Free rotation is possible with respect to a C-C bond in the case of alkanes. b) Draw Newman's projections of the two conformers of ethane. Which among these is more stable? Justify.

Free rotation is possible with respect to a C-C bond in the case of alkanes. c) An alkene on ozonolysis followed by reduction of the ozonide formed with zinc and water gave a mixture of ethanal and methanal. i) Identify the alkene

Free rotation is possible with respect to a C-C bond in the case of alkanes. c) An alkene on ozonolysis followed by reduction of the ozonide formed with zinc and water gave a mixture of ethanal and methanal. ii) Illustrate the above mentioned the above mentioned reaction using the chemical equation.

The IUPAC names of alkanes are based on their chain structure. Name the type of bond fission resulting in the formation of free radicals.

A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations. i) Represent Sawhorse and Newman projection formulae of staggered and eclipsed conformation of ethane.

Why do the 'C-C' bonds rather than 'C-H' bonds break during cracking of alkanes?

The bond dissociation energy of B-F in BF_3 is 646 kJ mol^(-1) , whereas that of C-F in CF_4 is 515 kJ mol^(-1) . The correct reason for higher B-F bond dissociation energy as compared to that of C-F is the : smaller size of B atom as compared to that of C atom.; stronger sigma bond between B and F in BF_3 as compared to that between C and F in CF_4 ; significant p pi-p pi interactions between B and F in BF_3 , whereas there is no possibility of such interaction between C and F in CF_4 ; lower degree of p pi-p pi interactions between B and F in BF_3 than that between C and F in CF_4
