What is the point group of naphthalene?

group D2h
Naphthalene belongs to the point group D2h.

What is the point group of dichloromethane?

Dichloromethane, CH2Cl2. There is a C2 rotation axis which passes through the carbon atom and the midpoints between the two hydrogen atoms and the two chlorine atoms. The four symmetry operations E, C2, σ(xz) and σ(yz) form the point group C2v.

What is symmetry of benzene?

The benzene molecule has a sixfold axis of symmetry along a line through the centre of the molecule and perpendicular to the screen. “6-” is a similar symmetry operation to 6+, but with a negative, i.e. clockwise, rotation angle of 60°.

What is the point group of 1/8 Dichloronaphthalene?

C2v
The point group is C2v. 4.4 a. Napthalene has three perpendicular C2 axes, and a horizontal mirror plane (regardless of which C2 is taken as the principal axis), making it a D2h molecule. 1,8-dichloronaphthalene has only one C2 axis, the C-C bond joining the two rings, and two mirror planes, making it a Czy molecule.

What is the dielectric constant of fluorobenzene?

In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C. It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. Fluorobenzene is a relatively inert compound reflecting the strength of the C–F bond.

What does the flash point of fluorobenzene look like?

Fluorobenzene appears as a clear, colorless liquid with a characteristic aromatic odor. About the same density as water. Flash point 5°F. Vapors heavier than air.

Which is lower PHF or fluorobenzene boiling point?

Its melting point at -44 °C is lower than that of benzene. In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C.

How is fluorobenzene used as a reagent?

FLUOROBENZENE appears as a clear, colorless liquid with a characteristic aromatic odor. About the same density as water. Flash point 5°F. Vapors heavier than air. May irritate the skin, eyes, and mucous membranes. Used as an insecticide, larvacide and as a reagent for plastic or resin polymers.
