B atom receives hybridised to type 3 equivalent hybrid orbitals directed in direction of three comers of equilateral triangle with B atoms in the centre. Bond angle = a hundred and twenty°.
Response: The molecular orbital fashioned by the subtractive result from the electron waves of the combining atomic orbitals, is referred to as antibonding molecular orbital.
This may take place in two techniques; by transfer of one or more electrons from one atom to other or by sharing of electrons involving two or even more atoms.
(b)The best rise in ionization enthalpy is seasoned on removing of electrons from Main noble fuel configuration.
A scholar traces the path of the ray of light through a glass prism for various angles of incidence. He analyses Every single diagram and attracts the following conclusion:
Structuring of Responses: It showcases the way to current answers in a very structured fashion to align with CBSE’s evaluation conditions.
Dilemma 4. Title various blocks of elements while in the periodic table. Give common Digital configuration of each and every block.
Variation inside of a team. On shifting down the team since the atomic dimension of The weather raises that’s why ionization enthalpy decreases down the team.
This component covers the structural areas of crops and animals at mobile, tissue, and organ stages, like:
Respond to: (a)Dipole moment: Within a polar molecule, a person conclusion bears a good cost and another provides a negative demand. Consequently, the molecule has two poles with equal magnitude of the charges. The molecule is called dipolar molecule and possesses dipole second.
Query ten. How do atomic radius change inside of a interval and in a gaggle? How does one explain the variation?
Hi, You will get admission into engineering colleges by way of administration quota In case you have not published or cleared any entrance Examination. But management quota is just not readily available for presidency engineering colleges.
ISC Class eleven has a multitude of topics that students can Decide on and pair with each other. People with a inclination towards enterprise and finance can batch Commerce, Accounts and Economics while The scholars CBSE Class 12 Chemistry with a prefer to pursue professional medical science can pick biology, chemistry or biotechnology.
Problem 21. Besides tetrahedral geometry, another probable geometry for CH4 is square planar Using the 4 H atoms on the comers of the square and the C atom at its centre. Make clear why CH4 just isn't sq. planar?
