Bond strength in hydrocarbons
As much shorter is the bond size, the greater is the compression among molecules atomic nuclei and therefore greater is the strength of that bond.
Bond type (C - H)
Bond type (C - C)
Bond energy (kcal/mole)
(in alkanes)
104
80 - 90
(in alkenes)
106
122 - 164
(in alkynes)
121
123 - 199
Low value of electrode potential(Mn3+/Mn2+) for scandium shows Sc3+ is stable while comparitively low value of electrode potential(Mn3+/Mn2+) for vanadium shows Vn2+is stable.Why?
Among the bonds formed by a chlorine atom with atoms of hydrogen, chlorine, sodium and carbon, the strongest bond is formed between (1) H- cl
(a) Explain in terms of ionic equilibria why the aqueous solution of a salt derived from a weak acid and a strong base (e.g. sodium phenolate) has a pH greater than 7. (b) B
Reaction involving cleavage of with removal of 'H' as proton Alcohols are stronger acids as compared to terminal acetylene but are not acidic enough to react along with aqueous
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
A compound exists in 2 forms. One them produces 2moles of AgBr while the other produces 1mole of AgBr with AgNO3
