A bimolecular reaction is always a second-order reaction, but a second-order reaction is not always a bimolecular reaction.
The most important thing to take note of is that molecularity of a reaction is a concept applicable to only elementary reactions, meaning non-complex. In a way, elementary reactions are basic and achieved in one step. Complex reactions involve intermediate steps before achieving the desired reaction.
Molecularity is equal to the sum of the coefficients of the reactants, so two reactants give a second-order bimolecular reaction. However, second-order reactions can involve more than two reactants especially in complex reactions.

Explanation:
The valence shell electron pair repulsion theory ( VSEPR) gives the description of molecular geometry based on the relative number of electron pairs present in the molecule.
However, electron pairs repel each other, the repulsion between two lone pairs is greater than the repulsion between a lone pair and a bond pair which is also greater than the repulsion between two lone pairs.
The presence of lone pairs distort the bond angle and molecular geometry from the expected geometry based on VSEPR theory. Hence, in the presence of lone pairs of electron, the observed molecular geometry may be different from that predicted on the basis of the VSEPR theory, the bond angles also differ slightly or widely depending on the number of lone pairs present.
All the molecules in the question possess lone pairs, the number of electron pairs do not correspond to the observed molecular shape or geometry due to lone pair repulsion. Usually, the molecular geometry deals more with the arrangement of bonded atoms in the molecule.

Aphelion in miles =94290301
Perihelion in miles = 91200281
Explanation:
To convert km in mile we use the multiply the distance in km with 0.62, because there are 0.62 miles in 1 km.
Aphelion in miles = aphelion in km × 0.62
Aphelion in miles = 152081132 × 0.62
Aphelion in miles =94290301
Perihelion in miles = perihelion in km × 0.62
Perihelion in miles = 147097229 × 0.62
Perihelion in miles = 91200281
