a molecule, shaped like a ring
Benzene molecule is planar in nature. This is because like all carbons, it contains two spxpy hybrid carbon that form a hexagonal ring.
SO2 is bent shaped and has a net dipole moment.
No. There are two molecular requirements that must be met to indicate aromaticity. In order to be aromatic a molecule must: 1) have a ring of pi electrons above and below the molecule. This means: a. The molecule must be cyclic. b. All atoms in the ring must be sp2 hybridized c. The molecule must be planar. 2) have an odd number of pairs of pi electrons. Since acetic acid is not cyclic, it cannot meet the first requirement and therefore cannot be aromatic. There are, however, delocalized electrons that increase the stability of the compound.
An acyclic organic molecule is an open chain compound, for example alkanes and acyclic aliphatic compounds. A cyclic organic molecule is a molecule in which a series of atoms connect to form a loop or ring.
In organic chemistry, the word "residue" is synonymous with "moiety." These words just refer to some part of a molecule being discussed or not being discussed. Any organic [functional] group, whether it is a ketone, an ester, a vinyl group or a benzene ring can be referred to as the "ketone residue," "ester residue," "vinyl residue," etc. The word "residue" probably started being used when the organic group to which someone was referring was not part of, or was not being included in, some other part of a molecule being discussed. When someone is referring to the "ring" of a molecule, he is almost always talking about a benzene ring, although it is possible that he could be talking about any ring regardless of how many atoms it is comprised of or whether it is aromatic or not. But in general, just the word ring usually means a benzene, or phenyl, ring - same thing. For example, aspirin contains a benzene ring, a carboxylic acid group (attached to the ring), and an acetylated phenol moiety or group (also attached to the ring). Imagine an organic chemist is discussing with his coworkers ways to replace one of the hydrogen atoms on the methyl group with one chlorine atom. I can imagine one of the chemists saying something like "That method might work, but it might also chlorinate the ring residue."
No. At room temperature sulfur forms a ring-shaped eight-atom molecule.
Yes, ring galaxies are actually ring-shaped, with a circle-like appearance.
A ring is a cyclic molecule as benzene.
No molecule has the shape of a young goat.

ATOLL
The 33 ring-shaped bones of the spine are called the vertebrae.
The heart-shaped ring should be facing away from the wearer.
A ring shaped coral reef is called an Atoll.
Sugar. In it's solid form, it's a 6-member (non-aromatic - if you're keeping score!) ring. In most sugars, one of the atoms in the ring is an oxygen atom. The rest are carbons. When you dissolve it in water, the ring breaks and it becomes a linear molecule...
The cartilage in the larynx which is shaped like a signet ring is the cricoid cartilage. It is the only complete ring of cartilage around the trachea.
