Notice: Almost every other investigatory challenge, which entails about ten intervals of labor, can be picked out Along with the acceptance from the Trainer.
Concern 18. From bonding and antibonding molecular orbitals, which a person has lessen Vitality and which 1 has higher stability?
These available examine components are pretty ample to excel in your ISC Board exams. In order to down load them at once and make use of them to prepare to your board tests conveniently. Hyperlinks are supplied above.
Phosphorus atom is sp3 d hybridized within the psyched state. These orbitals are stuffed by the electron pairs donated by five Cl atoms as:
Both equally the juices pretty much comprehensive the whole process of digestion of proteins, starch, carbohydrates etcetera. When the meals is broken down, the compact intestine is dependable to absorb straightforward particles which include amino acids, glucose and many others.
(b) The fatty acids and glycerol are absorbed in the lacteals to enter the lymphatic technique which forms a network all over the system to in the long run vacant its contents to the blood stream.

It is because just after dropping an electron, sodium attains the secure noble fuel configuration. However, magnesium, soon after getting rid of on electron nonetheless has one particular electron.
The compounds dealt with right here, are reasonably plus the principles are novel, and for that reason the students are required to shell out special focus on the chapter.
Respond to: The 1st ionisation enthalpy of magnesium is greater than that of Na due to bigger nuclear charge and a little bit smaller sized atomic radius of Mg than Na. Following the loss of initial electron, Na+ shaped has the electronic configuration of neon (2, eight).
They are really remarkably reactive elements and CBSE Class 12 so takes place in blended state. On transferring down the group their reactivity boosts.
Question 2. The 1st ionisation enthalpy of magnesium is better than that of sodium. On the other hand, the 2nd ionisation enthalpy of sodium is a great deal greater than that of magnesium. Demonstrate.
Question 21. Aside from tetrahedral geometry, A different probable geometry for CH4 is square planar With all the four H atoms for the comers from the sq. and also the C atom at its centre. Demonstrate why CH4 just isn't sq. planar?
