An organic compound in which a carbonyl group is bonded to a nitrogen atom is a(n) 1) amide 2) aldehyde 3) ketone 4) ester

An organic compound in which a carbonyl group is bonded to a nitrogen atom is an amide.

Explanation:

An amide is an organic compound which has a carbonyl group and is bonded to a nitrogen atom.

If a carbonyl group lies between the nitrogen and the compound, then it is called an amide.

These (amides) are usually regarded as the derivatives of carboxylic acids or ammonia in which the hydroxyl group has been replaced by an amine or ammonia.

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
