The total number of C - C sigma bond/s in mesityl oxide C 6 H 10 O is (Round off to the Nearest Integer).

sigma bonds are the strongest type of covalent chemical bond. They are formed by head-on overlapping between atomic orbitals. Sigma bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups.

Mesityle oxide

$\therefore {\mathrm{C}}_{\overline{\mathrm{\sigma }}}\mathrm{C}=5$
