Elements are arranged in groups by similar atomic structure on the periodic table. This allows for an element's properties to be

predicted based on general periodic trends. One of these trends, electronegativity, increases up a group and to the right along a period and can be defined as the atom's ability to _______.
A) attract a core pair of electrons toward itself.
B) attract a bonding pair of electrons toward itself.
C) attract a valence pair of electrons toward itself.
D) attract a nonbonding pair of electrons toward itself.

Furan and maleimide undergo the Diels-Alder reaction at 25 °C to give the endo product. When the reaction takes place at 90 °C,
mafiozo [28]

Answer:see attached image

Explanation:

In organic chemistry, a product may be kinetically or thermodynamically favoured. A kinetically favours product forms faster, it may not necessarily be the more stable product. The thermodynamically favoured product forms at a slower rate but is more stable. Often times, the kinetically favoured product rearranges itself to form the thermodynamically favoured product at equilibrium. The endo product of the Diels Alder reaction mentioned in the question is first formed (kinetically favoured) but rearranges to form the exo product (thermodynamically favoured) at equilibrium. This is clear shown in the reaction mechanism attached below.

a 0.555 g sample of mayonnase was burned in excess oxygen inside a bomb calorimeter with a total heat capacity (bomb and water)
Fofino [41]

Answer:

Dietary\ Calories=65.6kcal

Explanation:

Hello!

In this case, since we can see that the heat released by the combustion of the mayonnaise is absorbed by the bomb calorimeter and water, we can set up the following equation:

m_{mayonnaise}q_{mayonnaise}=C\Delta T

Whereas q for mayonnaise stands for the heat due to its usage; thus, we plug in to obtain:

q_{mayonnaise}=\frac{5.20kJ/\°C*2.93\°C}{0.555g} \\\\q_{mayonnaise}=27.45\frac{kJ}{g}

Now, if 10.0 g are eaten, the energy provided by it turns out:

E_{mayonnaise}=27.45kJ/g*10.0g\\\\E_{mayonnaise}=274.5kJ

And we need that value in dietary calories, 1 kcal:

Dietary\ Calories=274.52kJ*\frac{1kcal}{4.184kJ}\\\\ Dietary\ Calories=65.6kcal

Best regards!

4. Arrange the following substances in order of increasing boiling point: CH3CH2OH, HOCH2CH2OH, CH3CH2Cl , and ClCH2CH2OH A. CH3
Studentka2010 [4]

Answer: Option (B) is the correct answer.

Explanation:

A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.

So, in the molecule HOCH_{2}CH_{2}OH there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.

In the molecule ClCH_{2}CH_{2}OH there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than HOCH_{2}CH_{2}OH.

In the molecule CH_{3}CH_{2}OH, there will be only hydrogen bonding. Hence, its boiling point is less than ClCH_{2}CH_{2}OH.

In the molecule CH_{3}CH_{2}Cl, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.

Therefore, we can conclude that increasing order of boiling point will be as follows.

        CH_{3}CH_{2}Cl < CH_{3}CH_{2}OH < ClCH_{2}CH_{2}OH < HOCH_{2}CH_{2}OH
