SATHEE: Chemical Bonding and Molecular Structure

Chemical Bonding and Molecular Structure - Result Question 83

####85. Which statement is NOT correct? [1990]

(a) A sigma bond is weaker than a $π$ -bond.

(b) A sigma bond is stronger than a $π$ -bond.

(d) A double bond is shorter than a single bond.

Show Answer

Solution:

(a) A $σ$ - bond is stronger than a $π$ -bond hence option (a) is not correct.

Sigma (s) bonds are formed by head on overlap of unhybridised $s - s, p - p$ or $s - p$ orbitals and hybridised orbitals $(s p, s p^{2}, s p^{3}, s p^{3} d .$ and $s p^{3} d^{2}$ ) hence $s$ bonds are strong bonds where as $P i (p)$ bonds are formed by side ways overlap of unhybridised $p$ - and $d$ -orbitals hence $p$ bonds are weak bonds.
