·   Complex numbers are required because they are used extensively in mathematics and physics. A complex number can be used to solve quadratic equation zeros. If we come across a negative in any square root, we can use complex numbers to simplify the zero. Complex numbers have applications in electronics and electromagnetism.

·        Algebraic properties of complex numbers – for complex numbers the properties of addition and multiplication are the same.

o   Closure property of addition – for any two complex numbers y1 and y2 the sum of y1 + y2 is also a complex number.

o   The commutative property – for any two complex numbers y1 and y2 we have y1 + y2 = y2 + y1

o   The associative property – for any two complex numbers y1, y2, and y3 we have (y1+y2)+y3 = y1+(y2+y3)

o   The additive identity – there exists a complex number 0 = 0+0i such that, for every complex number y, y + 0 = 0 + y = y. the complex number 0 = 0+0i is called the additive identity of complex number.

o   The additive inverse – for every complex number y there exists a complex number –y such that y+(-y) = (-y)+y = 0. –y is called the additive inverse of z.

 

·       Argand plane and polar representation of complex numbers – the complex number x+iy refers to the ordered pair (x,y) is geometrically represented as the unique point (x,y) in the XY- plane. For example, the complex number, 2+7i corresponds to the ordered pair (2,7) geometrically, and in the same way ordered pair -3+8i refers to the (-3,2).

·       Statement of Fundamental Theorem of Algebra – every polynomial equation of degree n also has complex number coefficients has n number of roots or solutions.

·       Solution of quadratic equations in the complex number system

·       Square root of a complex number

 NCERT Solutions Class 11 Maths is an important part of students’ preparation for their boards and competitive exam preparation.

NCERT Solutions Class 11 Chemistry Chapter 4 Chemical Bonding and Molecular Structure

Class 11 Chemistry NCERT Solutions Chapter 4 Chemical Bonding and Molecular Structure - Our solution is extremely beneficial for the preparation board exam. This NCERT Solution is an excellent study resource for mastering subject fundamentals. In-text questions and exercise questions have been thoroughly discussed in our NCERT Solutions Class 11 Chemistry Chapter 4 Chemical Bonding and Molecular Structure. This chapter covers a variety of topics.

·       Chemical bonding – Chemical bonding is the force of attraction between two chemicals that keep them attracted to each other. These connections are formed between atoms, ions, or molecules. Chemical bonds play an important role in the formation of chemical compounds.

·       Molecular structure – Molecular structure refers to the three-dimensional arrangement of molecules. The location of atoms but not electrons is described by a molecular structure.

·       Kossel-Lewis Method for Chemical Bonding - The formation of chemical bonds between two atoms was explained by Kossel-Lewis. They developed the electron theory of valence to explain the formation of the chemical bond.

·       Ionic or Electrovalent Bond - An ionic or electrovalent bond is formed when two oppositely charged ions come together. A chemical bond is formed by a positively and negatively charged particle. The positively charged ion is known as a cation, while the negatively charged ion is known as an anion.

·       Bond Parameters - To become stable, different atoms form a chemical bond. An anionic or electrovalent bond, a covalent bond, and a coordinate bond are all examples of bonds. This demonstrates that every bond possesses some properties. These bond properties are referred to as bond properties.

·       Valence Bond Theory - The valence bond theory explains electron density in a covalent bond by overlapping their valence atomic orbitals. This results in the formation of an electron pair density between the two atoms. Because these electrons are attracted to both nuclei, they hold the two atoms together.

·       Hybridization - The formation of a completely new orbital by combining two or more atomic orbitals from the same atom is known as hybridization. Hydrogen Bonding - A hydrogen bond is the electrostatic force of attraction between hydrogen atoms. Our NCERT Solutions Class 10 Chemistry course covers a wide range of topics.
