Sia ? 4 years, 6 months ago

Inductive Effect	Mesomeric Effect
1. It operates in saturated compounds.	1. It operates in unsaturated compounds especially having conjugated systems.
2. It involves electrons of a – bonds.	2. It involves electrons of π – bonds or lone pair of electrons.
3. The electron pair is slightly displace from its position and hence partial charges are developed.	3. The electron pair is completely transferred and hence unit positive and negative charges are developed.
4. It is transmitted over a short distance it becomes negligible after second carbon atom in the chain.	4. It is transmitted through the entire chain provided conjugation is present.

Roshan Pandey 7 years, 11 months ago

to fajan’s rule no bond is 100 % ionic but have some covalent charecter also ‘due to smaller size lithium has greater polarising power than sodium [largerin size than Li] hence greater covalent charecter in LiCl than NaCl hence NaCl is moreionic than LiCl.

Ashita Laxami 7 years, 11 months ago

In certain elements..the electrons in S orbital refuse to take part in chemical bonding..this is called inert pair effect.

Sweet Girl 7 years, 11 months ago

When any S-block element takes part in bonding with the P-block element it is known as inert pair effect

Why the ionization enthalpy dicreases down the group?

Posted by Hamdan Hamdan 7 years, 11 months ago

CBSE > Class 11 > Chemistry

3 answers

Osama Malik 7 years, 11 months ago

Ionisation enthalpy is amount of energy needed to remove most losely bonded electron from valence shell. As we move down the group the size increases and outermost or valence shell moves far away from neucleus. So it will be removed easily as effect of attraction of neucleus decreases.So ionisation enthalpy decreases.

Yashu Tyagi 7 years, 11 months ago

Due to increase in atomic size

1Thank You

A Z 7 years, 11 months ago

While moving down a group the atomic number increases and the number of shells also increases. As a result of it the outermost shell is far away from the nucleus so the ionization enthalpy decreases moving down a group.
