Answer:

1.The group is a constituent of carboxylic acids, esters, anhydrides, acyl halides, amides, and quinones, and it is the characteristic functional group (reactive group) of aldehydes and ketones. Carboxylic acids (and their derivatives), aldehydes, ketones, and quinones are also known collectively as carbonyl compounds.

2.Amines are composed of a nitrogen atom bonded to some combination of carbons and hydrogens. Amines are weak bases commonly used in pharmaceuticals. Carbonyl is composed of a carbon atom double bonded with an oxygen atom, and is a common structural component of many other organic molecules.

3.Nitrogen forms many thousands of organic compounds. Most of the known varieties may be regarded as derived from ammonia, hydrogen cyanide, cyanogen, and nitrous or nitric acid. The amines, amino acids, and amides, for example, are derived from or closely related to ammonia

4.Halogenated compounds, or organic halides, are organic compounds that contain halogen atoms.

5.alcohol, any of a class of organic compounds characterized by one or more hydroxyl (―OH) groups attached to a carbon atom of an alkyl group (hydrocarbon chain).

6.The group is a constituent of carboxylic acids, esters, anhydrides, acyl halides, amides, and quinones, and it is the characteristic functional group (reactive group) of aldehydes and ketones. Carboxylic acids (and their derivatives), aldehydes, ketones, and quinones are also known collectively as carbonyl compounds.

7.Acetone is a powerful colorless solvent that is used to clean in the manufacturing process of many plastic, metal, and composite products. Common uses of Acetone include cleaner for grease, oil, resin, ink, permanent marker, adhesive, and paint.

8.A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule

9.The empirical formula represents the simplest whole-integer ratio of atoms in a compound. The molecular formula for a compound can be the same as or a multiple of the compound's empirical formula.

10.Chemical formulas, sometimes also called molecular formulas, are the simplest way of representing molecules. In a chemical formula, we use the elemental symbols from the periodic table to indicate which elements are present, and we use subscripts to indicate how many atoms of each element exist within the molecule.

11.hydrocarbon, any of a class of organic chemical compounds composed only of the elements carbon (C) and hydrogen (H).

12.Many hydrocarbons occur in nature. ... Aliphatic hydrocarbons are divided into three main groups according to the types of bonds they contain: alkanes, alkenes, and alkynes. Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond.

13.Alkanes. Alkanes, or saturated hydrocarbons, contain only single covalent bonds between carbon atoms. Each of the carbon atoms in an alkane has sp3 hybrid orbitals and is bonded to four other atoms, each of which is either carbon or hydrogen.

14.An alkene is a hydrocarbon with one or more carbon-carbon double covalent bonds. The simplest alkene is composed of two carbon atoms and is called ethene (shown below). Each carbon is bonded to two hydrogen atoms, in addition to the double bond between them.

15.Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings). Alkynes undergo many of the same reactions as alkenes, but can react twice because of the presence of the two p-bonds in the triple bond.
