(a)
To determine: The terpene compounds and isoprene units of terpenes.
Interpretation: The terpene compounds are to be predicted and circle around isoprene units of terpenes is to be drawn.
Concept introduction: An isoprene unit is made up of five-carbon atoms. In terpenes, the isoprene units are connected to each other in head to tail fashion. The head part of an isoprene unit is branched, whereas the tail part of an isoprene unit is unbranched.
(b)
To determine: If Vicks Vapo-Rub is optically active with an explanation.
Interpretation: The validation of the fact that Vicks Vapo-Rub is optically active is to be stated with an explanation.
Concept introduction: The optical activity of compound depends upon the number of chiral carbons and element of symmetry it have. Optically active compounds rotate plane of polarized light in right or left direction.

The existence of compounds of the noble gases was once a great surprise and stimulated a great deal of theoretical work. Label the molecular orbital diagram for XeF (include atom chemical symbol, atomic orbitals, and molecular orbitals) and deduce its ground state electron configuration. Is XeF likely to have a shorter bond length than XeF+? XeF XeF+ Bond Orderarrow_forward
