Does methylenecyclohexane obey Zaitsev's rule? why or why not
1 answer:
Answer:
Explanation: Zaitsev’s or Saytzev’s (anglicized spelling) rule is an empirical rule used to predict regioselectivity of 1,2-elimination reactions occurring via E1 mechanism or via E2 mechanism. It states that in a regioselective E1 or E2 reaction the major product is the more stable alkene, i.e., the alkene with the more highly substituted double bond.
E1 reaction always follow Zaitsev’s rule; with E2 reactions, there are exceptions (see antiperiplanar).

A solid with a unit cell that follows a structure to the face-centered cubic crystal would look like that shown in the attached picture. Thus, the model should consist of 8 balls, one for each corner of the cube. Also, It would need 6 balls, one at each center of the cube's faces. So, the answer is A.
The volume increased to 0.64 L on increasing the temperature to boiling point of water.
<u>Explanation:</u>
One of the important laws used for understanding the kinetics of gas particles is Charle's law. It states that the volume occupied by gas molecules will be directly proportional to the Kelvin temperature of the molecules at constant pressure.
Volume ∝ Kelvin Temperature at constant Pressure
So, in this case, the initial volume of the container in which Nitrogen gas is kept is given as 0.5 L and the initial temperature of the Nitrogen gas is said to be 18°C.
Now the container is heated to boiling point of water which is 100°C, then the volume occupied by the gas should increase as per Charle's law.
Since here V₁ = 0.5 L
T₁ = 18°C = 18 + 273.15 = 291.15 K
T₂ = 100°C = 100 + 273.15 = 373.15 K
Thus, the volume increased to 0.64 L on increasing the temperature to boiling point of water.
