Limitations of octet rule

Prakhar Jadaun ? 6 years, 11 months ago

1 . Elements like H and He exist since they donot complete their octet. They complete their duplate. 2 . Formation of hypervalent compound i.e. compounds having more than 8 electrons in their valence shell. Eg. SiF6 , in this Si have 12 shared pair electrons ( 6 of Si and 6 of F) . 3 . Formation of compound having less than 8 electrons in their valence shell. Eg. AlCl3, in which aluminum donot complete their octet, after been combined with three Cl, it has only 6 electrons in its valence shell

It cannot be applied to the nonmetals after silicon in the Periodic Table. These elements can “expand their octet” and have more than eight valence electrons around the central atom. Molecules with an odd number of electrons such as NO and NO₂ cannot satisfy the octet rule.

Radius of gyration or gyradius of a body about an axis of rotation is defined as the radial distance of a point from the axis of rotation at which, if whole mass of the body is assumed to be concentrated, its moment of inertia about the given axis would be the same as with its actual distribution of mass.

Ayushi Ayushi 6 years, 11 months ago

in SiCl6(2-) the chlorine atom is much larger than flourine which does not allow the six chlorines to surround the silicon due to repulsions between chlorine atoms. silicon cannot acomodate 6 chlorines around it. Hence , due to interelectron repulsions between chlorine atoms the compound SiCl6(2-) is unstable and not known.

Ayushi Ayushi 6 years, 11 months ago

Fluid pressure is a measurement of the force per unit area on a object in the fluid or on the surface of a closed container. This pressure can be caused by gravity, acceleration, or by forces outside a closed container. Since a fluid has no definite shape, its pressure applies in all directions.

Akash Kumar 6 years, 11 months ago

When 680nm light is provided to PSll the electron in it get excited & jump to an orbital farther from it & accepted by a e- acceptor. When the intensity of light reaches 700nm, the e- from e- acceptor transferred to PSl. The e- in PSI get excited & finally received by NADP+. The e- moves throughout the process with the help of e- transporter. Hence the movement of e- is controlled by electron transport system (ETS).

Explain trend of electron gain enthalpy in the periods & group

Posted by Akash Kumar 6 years, 11 months ago

CBSE > Class 11 > Chemistry

2 answers

Ayushi Ayushi 6 years, 11 months ago

The electron gain enthalpy of halogens is highly negative because it needs only one electron to achieve nearest noble gas configuration. And for noble gases, it is highly positive because the extra electron has to be placed in the next higher principal quantum level which requires lots of energy.

4Thank You

Ayushi Ayushi 6 years, 11 months ago

Electron gain enthalpy (ΔegH) is defined as the enthalpy change associated with an isolated gaseous atom (X) when it gains an electron to form its corresponding anion. The reaction can be given as below: X(g)+e−→X−(g) On the basis of nature of the element, the process of accepting electron in an atom can either be exothermic or endothermic. In general, energy is released when an electron is added to an atom and the electron gain enthalpy for such elements is negative.

Re-absorption: As the filtrate flows along the tubule useful substances such as glucose, amino acids, salts and water are selectively re-absorbed into the blood by capillaries surrounding the nephron tubule.
The amount of water re-absorbed depends on the need of the body and also on the amount of wastes to be excreted.
