As being the axial bond pairs suffer additional repulsion entrance the equatorial bond pairs, axial bonds are a bit more time than equatorial bonds.
Exercise ISC twelfth issue papers to know the Examination sample, marking scheme and issues level of issues asked in past a long time.
As a consequence of two lone pairs of electrons on O-atom, repulsion on bond pairs is greater in H20 in comparison to NH3 . Hence, the bond angle is considerably less in H20 molecules.
Presented down below is usually a jumbled sequence of the different portions of the human alimentary canal. Rewrite them in accurate sequence.
Question 34. Produce the vital situations essential to the linear mix of atomic orbitals to variety molecular orbitals.
Rationalization: Ice has superior certain latent warmth of fusion. That means, it demands a lot of warmth to soften.

Reply: Octet rule: Atoms of factors Blend with one another to be able to full their respective octets so as to accumulate the steady gasoline configuration.
In NH3, the dipole times on the a few N—H bonds are in CBSE Class 12 Chemistry the exact same path as the lone pair of electron. But in NF3, the dipole times of the a few N—F bonds are while in the course reverse to that of the lone pair. As a result, the resultant dipole minute in NH3 is a lot more than in NF3.
In predicting the nature from the molecules: Molecules with precise dipole times are polar in mother nature and those of zero dipole moments are non-polar in mother nature.
