Problem

Identify each statement as either True or False.

MC1 Each resonance structure is in rapid equilibrium with all the other structures.

MC2 Each atom in all the resonance structures must have a complete valence shell of electrons.

MC3 Loss of hyperconjugation gives rise to angle strain.

MC4 A nitrogen atom is sp3 hybridized when it has three sigma bonds and no ability to form pi bonds with adjacent atoms.

MC5 Ring inversion of cyclohexane between two chair conformations occurs through a boat conformation intermediate.

MC6 Substituted cyclohexanes are destabilized by 1,3-diaxial steric strain.

MC7 The boat conformation of cyclohexane is more stable than the chair conformation.

MC8 The strongest intermolecular force between saturated hydrocarbons is dispersion forces.

MC9 A carbon atom in a ring can be chiral center if it bears two different groups, and the path traced around the ring from that carbon in one direction is different from the path traced in the other direction.

MC10 Hexane and 2,3-dimethylbutane are stereoisomers of each other.

MC11 A molecule that is superimposable on its mirror image is chiral.

MC12 trans-1,4-dimethylcyclohexane is an achiral molecule as it has a plane of symmetry.

MC13 Chiral molecules interact differently with certain types of light and with other chiral molecules.

MC14 Polarizability increases as the volume occupied by the electron cloud increases.

MC15 Boron is more electronegative as compared to nitrogen.
