What is a complex molecule?

COMPLEX MOLECULE. Such complex molecules are called polymers. They are possible because carbon atoms are able to form very stable bonds with other carbon atoms. Most of the molecules that make up living things are made of complex polymers.

In this manner, what are complex compounds?

A coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds. Ligands are Lewis bases – they contain at least one pair of electrons to donate to a metal atom/ion.

What is a complex ion?

A complex ion has a metal ion at its centre with a number of other molecules or ions surrounding it. These can be considered to be attached to the central ion by co-ordinate (dative covalent) bonds. (In some cases, the bonding is actually more complicated than that.)

What does it mean when you have a complex?

an emotional problem caused by unreasonable fears or worries. have/develop a complex about something: I used to have a complex about being in crowds. give someone a complex: If you keep telling her she’s clumsy, you’ll give her a complex.

Is a complex number?

A complex number is a number of the form a + bi, where a and b are real numbers and i is an indeterminate satisfying i2 = −1. For example, 2 + 3i is a complex number.

What are the different types of molecules?

All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.

  • Nucleic Acids. The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively.
  • Proteins.
  • Carbohydrates.
  • Lipids.
  • What is the definition of a building complex?

    Noun. 1. building complex – a whole structure (as a building) made up of interconnected or related structures. complex.

    What is the definition of a compound complex?

    compound-complex sentence. A sentence that contains at least two independent clauses and at least one dependent clause: “Queen Elizabeth I was called a redhead (independent clause), but no one knew her hair color for sure (independent clause) because she always wore a wig (dependent clause).”

    What is a complex in psychology?

    A complex is a core pattern of emotions, memories, perceptions, and wishes in the personal unconscious organized around a common theme, such as power or status. Primarily a psychoanalytic term, it is found extensively in the works of Carl Jung and Sigmund Freud.

    What is a molecular complex?

    A complex is a molecular entity formed by loose association involving two or more component molecular entities (ionic or uncharged), or the corresponding chemical species. The bonding between the components is normally weaker than in a covalent bond.

    What is complex substance in biology?

    the branch of biology that studies plants. catabolism. breakdown in living organisms of more complex substances into simpler ones together with release of energy. catalyst. substance that initiates or accelerates a chemical reaction.

    What are complex compounds?

    A coordination complex is the product of a Lewis acid-base reaction in which neutral molecules or anions (called ligands) bond to a central metal atom (or ion) by coordinate covalent bonds. Ligands are Lewis bases – they contain at least one pair of electrons to donate to a metal atom/ion.

    What are molecules used for?

    Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. Examples of such elements are oxygen and chlorine.

    What is a complex organic compound?

    Organic compounds are any molecules that are composed of the element carbon. The four main groups of carbon molecules of life are the most complex organic compounds: proteins, carbohydrates, lipids, and nucleic acids. All complex organic molecules are polymers.

    What is meant by complex in chemistry?

    In chemistry, a coordination complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

    What does it mean to be an organic compound?

    Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.

    What do compounds need to be organic?

    Proteins. Proteins, among the most complex of all organic compounds, are composed of amino acids (see Figure 2-4), which contain carbon, hydrogen, oxygen, and nitrogen atoms. Certain amino acids also have sulfur atoms, phosphorus, or other trace elements such as iron or copper.

    What are molecular characteristics?

    atoms properties hydrogen oxygen. All molecules have a definite mass and size that are dependent on the atoms from which the molecule is made. When atoms join other atoms to form molecules, the chemical and physical properties of the compounds are different from those of the elements from which they were formed.

    What is an example of an organic molecule?

    The presence of nitrogen, oxygen, and other atoms adds variety to these carbon molecules. Four important classes of organic molecules—carbohydrates, lipids, proteins, and nucleic acids—are discussed in the following sections.

    What does it mean to be an organic molecule?

    organic molecule. A molecule of the kind normally found in living systems. Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.

    What is the maximum number of atoms that carbon can bond to?

    A fundamental element, important for living, there are four different types of bonds carbon can form. The bonds formed are called covalent bonds, which are created when two atoms share an electron (i.e. valence electrons) with each other.

    What is a complex ion?

    A complex ion has a metal ion at its centre with a number of other molecules or ions surrounding it. These can be considered to be attached to the central ion by co-ordinate (dative covalent) bonds. (In some cases, the bonding is actually more complicated than that.)
