What is the product of the reaction of bromoethane with each of the following nucleophiles? a. CH3CH2CH2O− b. CH3C‚C- c. (CH3)3N d. CH3CH2S-

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

By rearranging the ideal gas law, P=n(RTV)=nconst, it can be demonstrated that the pressure of a sample of gas is directly proportional to the number of moles of gas present when volume and temperature are maintained constant. The common measurement of pressure is the pascal (Pa). The kilopascal is the most practical measure for measuring commonplace gas pressures since a pascal is a relatively tiny unit of pressure (kPa). There are 1000 pascals in a kilopascal. The atmosphere is yet another widely used pressure measurement unit (atm).

As nicely discovered earlier, the greater delocalised electrons gift and the smaller the radius of the atom, the better the melting factor of the metallic. As we circulate throughout duration three the quantity of delocalised electrons consistent with metallic atom will increase and the radius of the factors decreases. This way the melting factor will increase.

The electrons that are shared, lost, or gained are called valence electrons. The charge an ion will have after gaining or losing electrons is indicated by the oxidation number.

According to the octet rule, elements interact with one another to form a noble gas electron configuration by either gaining electrons or losing them. The number of electrons in an element's outermost shell is known as its valency, whereas the number of electrons an element has gained or lost in a compound is known as its oxidation state. The primary distinction between valency and oxidation state is this. Each shell can hold a maximum of half the number of elements in the corresponding period in terms of electrons.

What is metal leaf electroscope ?

Gold leaf electroscop has two gold leafs suspended from a metal(usually brass) stem in a vacuumed glass jar and connected to a metal cap.  The glass is grounded with the help of a metal foil to make it uncharged. It can be used to:
Detect charge: Body under test is touched with the metal cap. If the leaves diverge, the body is charged and if there is no effect on leaves, then the body is uncharged.
To identify the nature of charge: The electroscope is charged by a known body(say positively charged body) and then the body is removed. Next, the body under test is brought in contact with the metal cap. If the leaves diverge further, the body has same charge(positive) and if the leaves come closer to each other, the body has opposite charge(negative).
Identify a body as conductor or insulator: Take two electroscopes. Charge one of the electroscopes so that its leaves will diverge. Then, connect the two electroscopes by the object under test. If the leaves of other electroscope diverge, the body is a conductor and if there is no effect on the electroscopes, the body is an insulator.

In the periodic table, we notice that elements move up or down a column, they are grouped together into groupings with comparable chemical properties.

The periodic table is reflected in the patterns and trends in its rows and columns. Elements are grouped together into groups that have similar chemical characteristics as they move up or down a column. The atoms trend smaller or larger in size, and their reactivities fluctuate left to right within a row.

Beyond periods and groups, the periodic table divides elements into four groups called blocks: the s block, the p block, the d block, and the f block. These groups provide more information about the arrangement of the electrons, who their likely neighbors are in the table, and which electrons are their valence electrons.

The compound of T and X is most likely to involve covalent bonding.

The ability of an atom or functional group to draw electrons to itself is known as electronegativity in chemistry. An atom's electronegativity is influenced by both its atomic number and how far away from its charged nuclei its valence electrons are located.

The differences in the electronegativities are:

Q and Z : 4.0-0.9 = 3.1

R and X : 3.0-1.0 = 2.0

T and Z : 2.8-0.9 = 1.9

T and X : 3.0-2.8 = 0.2

Q and T : 2.8 - 0.9 = 1.9

Smallest difference in electronegativity causes a higher overlap in the orbitals of the shared electrons.

It is expressed in volts or millivolts. Greater reduction potential is indicated by larger positive reduction potential readings. High enthalpy of atomization and low enthalpy of hydration characterise copper. Because the considerable energy required to convert Cu(s) to Cu(aq)2+ is not offset by hydration enthalpy, the value of E(Cu2+/Cu) is unusually positive.

There are three primary types of chemical bonding such as ionic bond, covalent bond, and metallic bond.

A chemical bond is a lasting attraction between atoms or ions that enables the formation of molecules and crystals. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds, or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bonds" such as covalent, ionic and metallic bonds, and "weak bonds" or "secondary bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding. Strong chemical bonding arises from the sharing or transfer of electrons between the participating atoms.

There are three primary types of bonding: ionic, covalent, and metallic.

An ionic bond is formed when valence electrons are transferred from one atom to the other to complete the outer electron shell.Example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom.

A covalent bond is formed when the valence electrons from one atom are shared between two or more particular atoms.Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

A metallic bond is formed when the valence electrons are not associated with a particular atom or ion, but exist as a "cloud" of electrons around the ion centres.Metallic bonding is especially common in minerals involving transition metals. Gold, silver, and copper are examples of minerals with metallic bonds.
