In contrast to most ortho-para-directing groups, halides have a tendency to deactivate benzene. Two characteristics can be used to explain this peculiar behavior:

1. Inductive withdrawal, or the removal of electrons from the benzene’s carbon atom, is caused by the halogens’ extreme electronegative nature.

2. The halogens can donate electron density through pi bonding (resonance donation) because their electrons do not form bonds.

Option C is the right one.

When ethyne is oxidized with the strong alkaline KMnO4, glyoxal is produced. This is then further oxidized to yield oxalic acid as the final product.

Since the weight of one mole of monoatomic gas is equal to the gas’s atomic mass,

xg => 22.414dm3

20g is equal to 44.8dm3.

x = 10g.

The total of all the reactant exponents in the rate equation represents the reaction’s order. because the reactant exponents in this equation add up to 1. In this instance, the order of reaction is 1.

With 46% nitrogen, urea has the highest nitrogen content of any solid fertilizer.

All of the axes in triclinic crystals are uneven, and no angle is 90 degrees.

When an atom or molecule’s electrons are dispersed unevenly around the nucleus, it can produce a transient (instantaneous) dipole due to the electrons’ continuous motion. Any two neutral molecules that are nearly touching each other have dispersion forces. When polar molecules are present, INDUCED dipoles are created when one or more of the polar molecules causes the other molecule to become charged.

Mustard gas is a common name for beta and beta prime dichloro ethyl sulfide.

The color of bromine water (Br2(aq)) is reddish brown. When any unsaturated hydrocarbon (1-Pentene or 2-Methy1-1-pentene) is encountered, it is used to identify the unsaturation. Water containing bromine loses its color.

Humans and other animals both contain globulin proteins. Globulins are a class of proteins that are frequently present in blood plasma and have a variety of uses, including the transportation of lipids, ions, and antibodies. These proteins play vital roles in preserving general health in animals, including humans, and are an integral part of the immune system.

Transport globulins, which attach to and move molecules like hormones, vitamins, and metals, and immunoglobulins (antibodies), which the immune system produces to identify and eliminate foreign substances in the body, are examples of globulins.

Higher volatility, or a higher rate of evaporation, indicates that intermolecular forces are weaker and can be readily overcome, allowing molecules to escape from the liquid’s surface. A mixture of flammable and volatile hydrocarbons makes up gasoline. The instantaneous dipole-induced dipole forces between hydrocarbons are weak. Strong intermolecular forces called hydrogen bonds, which take more energy to break, are present in both alcohol and water. Honey has the strongest intermolecular forces of attraction (more hydrogen bonds) due to its high density and high viscosity.

Since pKa is inversely proportional to the Ka value, Option D would have the highest pKa value because it contains the least acidic compound of the compounds listed.

Chemically, we have a stronger -O-H bond because the compound has more electron-donating alkyl groups attached, which makes it harder for the H+ to break off. Alcohol becomes the least acidic as a result.

A collection of numerical values known as quantum numbers are used to characterize the characteristics of electrons in atoms. The Schrödinger equation, a mathematical formula that characterizes the behavior of electrons in an atom, is solved using these numbers. An atom’s electrons’ energy levels and wave functions can be determined using the Schrödinger equation, a foundational formula in quantum mechanics. The various energy levels and orbitals that electrons can occupy within an atom can be identified and described using the quantum numbers.

In its free state, an element’s oxidation number is always zero.

Option D is the right response because the order of reactivity of alkenes with hydrogen halide decreases down the group.
