Question

Saturated carbon compounds are usually not very reactive because:
A. C-C are very weak
B. C-C are very strong
C. They require heat for reaction
D. Both a and c

Answer 1

Hint: Saturated carbon compounds are the compounds that have all C-C bonds as single bonds. These are organic hydrocarbon chains. The hydrocarbons with double bonds and triple bonds are unsaturated carbon compounds.

Complete step by step solution:
Saturated carbon compounds with C-C single bonds are called alkanes. Alkanes as a class are characterized by a general inertness to many chemical reagents. C-C and H-H bonds are quite strong. They do not break unless alkanes are heated to very high temperatures. Because carbon and hydrogen have nearly the same electronegativity, the carbon and hydrogen bonds are only slightly polarized. As a consequence they are generally unaffected by most of the bases. Bonds in alkanes are covalent hence do not break easily to react.
Molecules of alkanes have no unshared electrons to offer as sites for attack by acids. This low reactivity of alkanes towards many reagents accounts for the fact that alkanes are originally called as paraffins.
This term paraffin, however, is not an appropriate one. We all know that alkanes react vigorously with oxygen when an appropriate mixture is ignited. This combustion occurs in the cylinders of automobiles and in oil furnaces, for example. When heated, alkanes also react with chlorine and bromine and they react explosively with fluorine.

Therefore from the above we can conclude that the correct option is C.

Note:
The conversion of C-C double and triple bond to single bond can be synthesized by hydrogenation reaction carried under the catalysts like platinum and nickel etc.
