Which of the statements about the properties of the carbon-carbon double bond is not true? Group of answer choices Whenever the
ella [17]

Answer:

Whenever the two groups on each end of a carbon-carbon double bond are the same, two diastereomers are possible.

Explanation:

Double bonds are formed when four electrons are shared between two carbon atoms. The second bond is generally known as a pi-bond while the first bond is called a sigma bond.

The presence of a double bond in a compound leads to restricted rotation about the carbon-carbon double bond. Hence the substituents are 'locked' in a particular configuration.

The more substituted a double bond is, the more stable it is according to Saytzeff's Rule.

Due to steric effects, trans alkenes are generally more thermodynamically stable than cis alkenes since trans alkenes have bulky groups oriented apart from each other.

All these are true statements. The answer selected must be the untrue statement.

2. HOW MUCH HEAT IS REQUIRED TO BE RELEASED WHEN
jarptica [38.1K]

Answer: -112200J

Explanation:

The amount of heat (Q) released from an heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of water vapour = 30.0g

C = 187 J/ G°C

Φ = (Final temperature - Initial temperature)

= 100°C - 120°C = -20°C

Then apply the formula, Q = MCΦ

Q = 30.0g x 187 J/ G°C x -20°C

Q = -112200J (The negative sign does indicates that heat was released to the surroundings)

Thus, -112200 joules of heat is released when cooling the superheated vapour.

Which of the following is not a characteristic of electromagnetic waves
Mekhanik [1.2K]

<u>Complete Question:</u>

Which of the following is not a characteristic of electromagnetic waves?

a. they can travel through a vacuum.

b. they can travel at various speeds through any one material.

c. they can be refracted.

d. they can be reflected.

<u>Correct Option:</u>

"They can travel at various speeds through any one material" is not a characteristic of electromagnetic waves.

<u>Explanation:</u>

It is a form of energy generated by interference from the oscillating magnetic and electric recorded. So we may conclude that it is created by moving electric charged particles through the vacuum so matter. This is a wave in which the two vectors vibrate each other perpendicularly and in the direction of the wave. Electromagnetic waves which involve gamma-rays, x-rays, ultraviolet rays, infrared-rays, microwaves and radio-waves can be featured by:

  • They may pass through the vacuum.
  • They are allowed to move through the matter and are reflectable.
  • They can pass through all of the material at the same pace. This means there is still constant speed of light, which is, they can be refracted.
