Thursday, August 18, 2011. STRENTH OF BONDS WITH OTHER ELEMENTS. The C-C and C-H bonds in organic compounds are very strong.These bonds generally do not break easily during the reactions.However;other atoms or groups such as Cl,OH,etc.,attached to the carbon atom may get replaced easily.For example,aqueous KOH reacts with haloalkanes to give the corresponding alcohol CH3-CH2-Cl KOH(aq) = CH3-CH2-OH KCl chloroethane ethanol.
