Symmetry is a property of molecules having more than one atom of the same kind, with equal bond lengths and/or bond angles. As like the high symmetry of the SF6 molecule (Fig. 1. arises from the six equal S-F bonds disposed at angles of 90° to each other. In order to build the notion more precise we use the idea of a symmetry operation. For example rotating SF6 by 90° about an appropriate axis, it appears indistinguishable after the rotation. The axis concerned is known as the symmetry element. Rotations which do not leave the molecule looking the similar are not symmetry operations.
Aldehyde is a carbonyl compound in which one valency of carbonyl carbon is satisfied by hydrogen atom and other by a alkyl group.
The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light ab
what evidence is there that all cells have a common ancestor?
Explain experimental evidence to demonstrate the existence of ferromagnetic domains. Temperature increases, thermal motion, or entropy, competes with ferromagnetic tendency for
Q. Briefly explain about Alloys? Ans. Pure metals are malleable. Metals that are harder, stronger and less malleable are sometimes required. These characteristics may be a
Yes, the basic character decreases due to resonace. This is because resonance is strongly linked to conjugation and hyperconjugation. Due to the pi-lp conjugation, the electon dens
