The high polarity of the oxygen-carbon bond in alcohols is what allows them to be soluble in water.

Anna11 [10]

This is false. An alcohol does indeed have a polar C-O single bond, but what we should really be focusing on is the extraordinarily polar O-H single bond. When oxygen, fluorine, or nitrogen is bound to a hydrogen atom, there is a small (but not negligible) charge separation, where the eletronegative N, O, or F has a partial negative charge, and the H has a partial positive charge. Water has two O-H single bonds in it (structure is H-O-H). The partially negative charge on the O of the water molecule (specifically around the lone pair) can become attracted either a neighboring water molecule's partially positive H atom, or an alcohol's partially positive H atom. This is weak (and partially covalent) attraction is called a hydrogen bond. This is stronger than a typical dipole-dipole attraction (as would be seen between neighboring C-O single bonds), and much stronger than dispersion forces (between any two atoms). When the solvent (water) and the solute (the alcohol) both exhibit similar intermolecular forces (hydrogen bonding being the most important in this case), they can mix completely in all proportions (i.e. they are miscible) in water.

Does sodium (Na) and argon (Ar) on the periodic table have similar properties? Explain in terms of location on the periodic tabl

iVinArrow [24]

Sodium (Na) and Argon (Ar) on the periodic table does not have similar properties.

PERIODIC TABLE:

Periodic table is the organized table that showcases the position of elements. The periodic table is organized into groups and periods.

Groups of the periodic table is in a vertical format labeled 1 - 7 while the period is in a horizontal format labeled 1 - 7.

Elements in the same group have the same number of valence electrons and hence, possess similar chemical properties.

Sodium (Na) belongs to group 1 while argon is a noble gas, hence, they are not in the same group of the periodic table and cannot have same properties.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Question no 1:</h2><h3>CATION:</h3>

Cation is the postively charged unit which is formed by the transfer of one or more electrons. It is attracted towards cathode thus it is called the CATION.

<h2>_____________________________________</h2><h2>Question no 2:</h2><h3>IONIC BOND:</h3>

Ionic bond is the type of bond which is formed between the positive and negative ions. It is mostly formed between the Metals (i.e. group 1 and 2) and Non metals (i.e. mostly group 7). The positive charge on metal is due to the loosing of electron and negative charge on non metal is due to accepting the electron.

<h2>_____________________________________</h2><h2>Question no 3:</h2><h3>POLYATOMIC ION:</h3>

A molecular ion is a covalently bonded set of two or more atoms, that can be considered to behave as a single unit, it also has a charge on it.

<h2>_____________________________________</h2><h2>Question no 4:</h2><h3>CONDUCTIVITY:</h3>

Conductivity is more in liquid than in solid because the conductivity is flow of electron and the movement is less in solid than liquids thus the solid has less conductivity. The liquid has more movement of molecules due to which there is more conductivity.

<h2>_____________________________________</h2><h2>Question no 5:</h2><h3>FORMULA UNIT: </h3>

Formula unit is a emperical formula used to express the ions in ionic compounds. It is the least whole number ratio of the ions present in the ionic compound.

<h2>_____________________________________</h2><h2>Question no 6:</h2><h3>CRYSTAL LATTICE:</h3>

Crystal lattice is the arrangement of atoms, molecules, or ions of a crystal in the form of a three dimensional space lattice.

<h2>_____________________________________</h2><h2>Question no 7:</h2><h3>ANION:</h3>

Anion is the negative charged because It receives one electron from the cations thus becomes negatively charged entity. It is attracted towards the positive anode thus it is called anion.

<h2>_____________________________________</h2><h2>Question no 8:</h2><h3>MOLECULES:</h3>

Ionic bond do not form molecules, They form the ions.

<h2>_____________________________________</h2><h2>Question no 9:</h2><h3>Attraction:</h3>

One type of bonding i.e. ionic bonding is formed by the attraction between the positive and negative ions.

<h2>_____________________________________</h2><h2>Question no 10:</h2><h3>LATTICE ENERGY:</h3>

It is the amount of energy required to change the state of matter.
