Organic Chemistry
How do heat and light initiate radical formation reactions?
Free radicals are generated due to the homolytic bond cleavage, a type of bond breaking where each atom holding the two-electron covalent bond gets one electron. Such a homolytic bond cleavage requires an input of energy, either in the form of heat or light.
Identify the Organic Compound with Molecular Formula C8H16O2- Aldehydes, Ketones and Carboxylic Acids
An Organic Compound 'A' molecular formula C8H16O2 was hydrolyzed with dilute H2SO4 to give a carboxylic acid 'B' and an alcohol 'C.' Oxidation of 'C' with chromic acid also produced 'B.' On dehydration 'C' gives 1-but-ene. Write the equations for the reaction involved.
1) The first step is find out the Degree of Unsaturation (the number of double bonds or the presence of a ring) in the compound.
The formula is,
Molecular mass (Molecular weight)
Molecular mass is the sum of the masses of all the atoms in the molecule, denoted as m.
The mass of the atoms is measured in the average atomic mass unit, a weighted average of all the element's naturally occurring isotopes.
The sum is represented in amu (μ) or Da unit.
Metallic Bond
A metallic solid is made of many metal atoms composed of kernels and electrons, the positive kernels held in arrays while the negative electrons float around them, at the same time, attracted to each other due to their opposite electrostatic nature and engaged in bonding known as the metallic bond.
What are the requirements of van der Waals force?
The van der Waal forces of interactions are weak intermolecular forces. For the atoms or molecules show these interactions only under certain conditions -
1) Distance- van der Waal forces mainly depend on the distance between the associated molecules. These forces become very weak if the distance between the molecules or atoms is greater. These forces are relatively stronger if the atoms or molecules are grouped closely.
What is a Bond Angle? How are bond angles formed?
The bond angle is the angle at which two adjacent bonds converge and meet at the central atom in molecules.
Why are Keesom forces are said to have an orientation effect?
Keesom forces occur in polar molecules where the atoms have a considerable electronegativity difference, resulting in the charge separation and formation of positive and negative poles. The negative pole of one molecule electrostatically interacts with the positive pole of the neighboring molecule. Consequently, all the polar molecules in the medium try to orient their dipoles to be in alignment for such electrostatic interactions.
Hydrogen Bond Strength, Significance, and Types
Learning Objective: To study the types of hydrogen bonds, hydrogen bond strength, and significance with examples.
Skill Level – Intermediate
Prerequisites:
Atom
The matter is composed of invisible, indivisible, innumerable particles called atoms. Atoms are responsible for giving each matter its unique properties and identity. The uniqueness comes from the nature of the atom and its composition. Atoms are composed of three subatomic particles- electron, neutron, and proton. For example, an Oxygen atom has 8 electrons, 8 protons, and 8 neutrons.
