(If he were virtuous & good, he would become a Great Horned Owl). In British folklore, a screeching Barn Owl is believed to predict that a storm or cold weather was imminent. During a storm, if a Barn Owl was heard, it indicated that the storm was nearly over.
Carbon group. The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). In modern IUPAC notation, it is called Group 14. In the field of semiconductor physics, it is still universally called Group IV.
1 This compound has the carbonyl group between two alkyl groups, so it is a ketone. 2  One alkyl group has three carbon atoms and is attached by the middle carbon atom; it is an isopropyl group. 3  A group with one carbon atom is a methyl group.he next functional group we consider, the carbonyl group, has a carbon-to-oxygen double bond. Carbonyl groups define two related families of organic compounds: the aldehydes and the ketones. Note. The carbonyl group is ubiquitous in biological compounds.
