A σ - bond is stronger than a σ -bond hence option (a) is not correct. Sigma (σ) bonds are formed by head on overlap of unhybridised s–s, p–p or s–p orbitals and hybridised orbitals (sp, sp², sp³, sp³d and sp³d²) hence σ bonds are strong bonds. Where as Pi (π)-bonds are formed by side ways overlap of unhybridised p- and d orbitals-hence σ bonds are weak bonds.

View answer

For nomenclature of alkenes in the IUPAC system, the longest chain of carbon atoms containing the double bond is selected. Numbering of the chain is done from the end which is nearer to the double bond. The suffix ‘ene’ replaces ‘ane’ of alkanes. The first member of the alkene series is: CH2 (replacing n by 1 in CnH2n) known as methene but has a very short life. The first stable member of the alkene series is C2H4 known as ethylene (common) or ethene (IUPAC). Q. The correct statement/s for nomenclature of alkenes in the IUPAC system is/are
