The kinetic theory state about the relationship between the speed and temperature of gas molecules "As the temperature increases, the speed of gas molecules increases".

Option: C

Explanation:

The temperature relates to a gas, according to the kinetic theory of gases, influences the rate of motion of the gas particles. The higher the gas temperature, the faster the gas particles are moving; the reverse is true, too.

This is because the gas particles gain more kinetic energy as the temperature of the gas increases, and therefore move faster and collide more with each other and the container walls.The rate of a gas's molecules is proportional to the temperature, and is inversely proportional to the gas's molar mass.

Answer: B. CH₂OH

Explanation:

First off, we need a liquid solvent. Eliminate C and D.

Now, we have to consider polarity.

Carbon tetrachloride is nonpolar, so sodium chloride will be insoluble.
CH₂OH is polar, so sodium chloride will be soluble.

why do elements in the same group have similar properties and how does this affect bonding capabilities ?

Alina [70]

Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.

If the SN2 reaction of an aromatic alcohol with an alkyl halide, like the synthesis of nerolin, is successful, what changes woul

bixtya [17]

Answer:

O-H stretch signal at 3300 cm-1

Explanation:

In this question, we can start with the reaction mechanism for the synthesis of Nerolin. We have to start with naphthalen-2-ol adding NaOH we can produce the alkoxide. Then this alkoxide can react by an Sn2 reaction with bromomethane to produce Nerolin (see figure 1).

In the starting molecule (naphthalen-2-ol) we have an "OH" group. Therefore we will have an O-H stretch signal around 3300 cm^-1. The alcohol signals are very broad and very intense, so this will be the main signal for the initial molecule. In the final product, we dont have the "OH" therefore this signal will disappear (see figure 2).
