(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.
We introduced the carbonyl group (C=O)âthe functional group of aldehydes and ketonesâin Chapter 14 Organic Compounds of Oxygen . The carbonyl group is also found in carboxylic acids, esters, and amides. However, in these compounds, the carbonyl group is only part of the functional group.A carboxylic acidAn organic compound that has a carboxyl group. is an organic compound that has a carboxyl groupA functional group that contains a carbonâoxygen bond and an OH group also attached to the same carbon atom. .earning Objectives. 1  Identify the general structure for a carboxylic acid, an ester, an amine, and an amide. 2  Identify the functional group for a carboxylic acid, an ester, an amine, and an amide.
