What is the difference between electronegativity and electroafinity

Posted by Manvi Dhariyal 4 years, 6 months ago

1 answers

Sia ? 4 years, 6 months ago

Given below are some of the key differences between electronegativity and electron affinity.

The property due to which the electron gets attracted to the atom is known as electronegativity. On the other hand, electron affinity is related to the release of energy when an electron gets added to an atom.
Electronegativity is qualitative while electron affinity is quantitative.
Electronegativity is generally a unitless quantity but is defined in regards to Pauling. Electron affinity, on the other hand, is measured in kJ/mol.
When an element tends to exhibit a stronger attracting ability, the electronegativity of that element is higher. However, electron affinity is higher if the nuclear charge of the element is higher.
The value of electronegativity generally lies between 0.7 to 3.98. On the other hand, electron affinity is known to be fixed since the electron releases almost a similar amount of energy when it is added to an atom.
The most electronegative element known is fluorine while the element having the highest electron affinity is chlorine.

What is a f- center?

Posted by Vishal Kumar 7 years, 4 months ago

CBSE > Class 12 > Chemistry

1 answers

Manvi Dhariyal 7 years, 4 months ago

An f centre or farbe centre or colour centre is a type of crystallographic defect in which an anionic vacancy in a crystal is filled by one or more unpaired electrons . Electrons in such a vacancy tend to absorb light in the visible spectrum such that a material that is usually transparent becomes colored. This is used to identify many compounds, especially zinc oxide (yellow).

Why H2O is a neutral and H2S is acidic

Posted by Shubham Thakur 7 years, 4 months ago

CBSE > Class 12 > Chemistry

2 answers

Manvi Dhariyal 7 years, 4 months ago

The S-H bond is weaker than the O-H bond, meaning that H2S more easily donates a proton and is therefore more acidic.

Difference between rate of reaction and rate constant

Posted by Gaurav Rana 4 years, 6 months ago

1 answers

Sia ? 4 years, 6 months ago

Rate of reaction is defined as the rate of disappearance of reactant and the rate of appearance of the product while rate constant is proportionality constant between the rate of reaction and the concentration terms. The rate of reaction depends on the concentration of the reactant.

G K 7 years, 4 months ago

The SN2 reaction is concerted. That is, the SN2 occurs in one step, and both the nucleophile and substrate are involved in the rate determining step. Therefore the rate is dependent on both the concentration of substrate and that of the nucleophile.......... The SN1 reaction proceeds stepwise. The leaving group first leaves, whereupon a carbocation forms that is attacked by the nucleophile.....
