What type of intermolecular forces does 2-methylbutane have

Answers

Answer 1

Answer: Covalent, as Isopentene (2 methylbutane) is completely non-metallic

Answer 2

Answer:

Final answer:

2-methylbutane, like similar molecules, exhibits the type of intermolecular force known as London dispersion forces due to its molecular structure of carbon and hydrogen atoms.

Explanation:

The substance 2-methylbutane exhibits the type of intermolecular forces known as London dispersion forces. These forces arise due to temporary shift in electron clouds causing temporary dipoles which induce dipoles in neighboring molecules. This is the simplest type of intermolecular forces and it can occur in all types of molecules, but is the dominant force in nonpolar and symmetrical molecules. Hydrogen bonding or dipole-induced forces do not play a role in this substance as its molecular structure of carbon and hydrogen atoms does not allow for those types of intermolecular interactions.

As the substance 2-methylbutane is a branched variant of butane, it has a slightly different structure, but this does not change the basic type of intermolecular forces present. Other similar molecules like propane and butene also exhibit similar types of intermolecular forces. Remember, intermolecular forces are not intramolecular forces which are much stronger and keep the atoms within a molecule together. Intermolecular forces are what keep molecules attached to each other which greatly effects physical properties of a substance like boiling point.

On the basis of electronegativity, which pair of elements is most likely to form monatomic ions? responses a. Ba and O b. Cs and Rb c. O and F d. Na and K

Answers

On the basis of electronegativity, elements that are far apart on the periodic table are more likely to form monatomic ions. This is because the larger the electronegativity difference between two elements, the more likely it is for one element to gain or lose electrons to achieve a stable electron configuration.

Out of the given options, the pair of elements that are the farthest apart on the periodic table is option d. Na (sodium) and K (potassium). Both sodium and potassium are in Group 1 (alkali metals), but potassium is located one period below sodium, making it more likely to form a monatomic ion due to the larger electronegativity difference.

Therefore, the answer is d. Na and K.

A helium-ﬁlled balloon contains 130 mL of gas at a pressure of 0.97 atm. What volume will the gas occupy at standard pressure?

Answers

Boyle's Law
G: V1= 130 mL
P1= 0.97 atm P2= 1 atm (standard pressure)

U: V2=?
F: V2 = V1 P1/P2

Answer : V2 = 126.1 mL volume of the gas occupy @ STP

When [OH-] changes from 10-9 to 10-11 in a solution: Kw = [H+][OH-]

What is the [H+] after the change?

Answers

According to the fact that [H+]*[OH-] is always equal Kw $= 1x10^(-14)$ , you can easily find concentration of [H+] by changing from $1*10^(-9)$ to $1*10^(-11)$
H increases, Kw is constant, therefore $10^-14 / 10^-11 = 10^-3.$
And you will have $Hence [H+] = 10^-3$ where pH is 3

Why are fibers birefringentbecause of the chemical makeup of the fiber

because the fiber is a natural fiber

because the fiber has long range order

because the fiber has a refractive index greater than 1.52

because the refractive index is less than 1.52

Answers

Answer:

Because of the chemical makeup of the fiber.

Explanation:

The birefringence is the difference between the refractive index of a fiber in a direction at parallel to the fiber axis and in a direction at right angles. It is caused by asymmetric core shape for the two axes, and majorly one of the manufacturing imperfections. It helps in controlling polarization property inside the fiber.

Inevitable manufacturing imperfections in optical fiber leads to birefringence, which is one cause of pulse broadening in fiber-optic communications. Such imperfections can be geometrical (lack of circular symmetry), due to stress applied to the optical fiber and/or due to bending of the fiber.
