Formaldehyde has a nonpolar trigonal planar molecule.
it is Trigonal Planar
sp2 Trigonal Planar
Explain the effect of molecular polarity on behaviour.

A sulfur molecule has zero polarity.
Yes.
H2CO; H2CO is polar, whereas CH3CH3 is nonpolar. H2CO has dipole forces in addition to LD forces. CH3CH3 only has LD forces.
Polarity of HF is nonpolar and it's molecular shape is linear.
The molecular shape of HCOOH is trigonal planar, I believe...
if molecular shape is symmatrical then its non-polar but if it is non symmatrical then its polar.
Explain the effect of molecular polarity on behaviour.
A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.
This molecule, like all other diatomic gas elements, is non-polar and has a rod-like shape.
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).

A sulfur molecule has zero polarity.
The simplest possibility is the same as the empirical formula, which is the molecular formula of formaldehyde, although it would probably more often be written as H2CO.
Yes.
