Rotation about a carbon-carbon double bond does not readily occur because: __________.1) the overlap of the p orbitals of the ca

rbon-carbon π bond would be lost2) the double bond is much shorter and therefore more difficult to rotate3) the overlap of the sp2 orbitals of the carbon-carbon σ bond would be lost4) the double bond is much stronger and therefore more difficult to rotate

Answer:

1) The overlap of the p orbitals of the carbon-carbon π bond would be lost

Explanation:

Unlike simple bonds, a double bond can not rotate, since it is not possible to twist the ends of the molecule without breaking the π bond.

In the structure of but-2-ene present in the attachment, we can see the two isomers, <em>cis</em> and<em> trans</em>. These isomers cannot be interconverted by rotation around the carbon-carbon double bond without breaking the π bond.

An acid with a H+ molarity of 1x10^-5 M has a ph of?
Pavlova-9 [17]

Answer:

The answer to your question is pH = 5

Explanation:

Data

[H⁺] = 1 x 10⁻⁵

pH = ?

pH is a measure of the hydrogen concentration. It measures the acidity or alkalinity. The range of pH goes from 0 to 14. The pH for an acid is from 0 to 6.9, for a neutral solution is 7.0 and for an alkali is from 7.1 to 14.

Formula

             pH = -log [H⁺]

-Substitution

             pH = -log [1 x 10⁻⁵]

-Simplification

             pH = - (-5)

-Result

             pH = 5

What pressure is exerted by 0.750 mol of a gas at 0 °C and a volume of 5
kow [346]

Answer: 3.4 atm

Explanation:

Given that:

Volume of gas V = 5L

(since 1 liter = 1dm3

5L = 5dm3)

Temperature T = 0°C

Convert Celsius to Kelvin

(0°C + 273 = 273K)

Pressure P = ?

Number of moles of gas n = 0.75 moles

Note that Molar gas constant R is a constant with a value of 0.0821 atm dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

p x 5dm3 = 0.75 moles x (0.0821 atm dm3 K-1 mol-1 x 273K)

p x 5dm3 = 16.8 atm dm3

p = (16.8 atm dm3 / 5dm3)

p = 3.4 atm

Thus, a pressure of 3.4 atm is exerted by the gas.
