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

The C-O bond order in CO_3^(2-) is

Which has the maximum bond energy of C-H bond ?

Free rotation is possible with respect to a C-C bond in the case of alkanes. a) The repulsive interaction between the adjacent bonds in a conformation is called…...

Substantiate the following statements. Although the C-H bond in acetylene has the greatest bond energy of all the C-H bonds, yet it is most acidic.

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. 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. ii) Illustrate the above mentioned the above mentioned reaction using the chemical equation.

Assertion: Dipolemoment ofphenol is smaller than that of methanol. Reason: In phenol C-O bond is less polar due to electron withdrawing effect of the benzene ring whereas in methanol, C-O bond Is more polar due to electron releasing effect of CH_3 group.
