Question

Compounds with single bond are stable than those with double or triple bonds.

• A. True
• B. False

Answer 1

The correct option is A True

Bond strength and stability are not the same concepts. Bond strength of a triple bond > Bond strength of a double bond > Bond strength of a single bond. This means to break all the three bonds in a triple bond, maximum energy is required. However, the triple bond represents a region of greater inter-atomic electron density ( 3 shared pair of electrons) than that of the double bond who's electron density is likewise greater than that of a single bond. In other words, the electrons binding multiple bonded atoms are more vulnerable to attack by electron-seeking species. Hence, unsaturated compounds react easily than saturated compounds.
