This cycloaddition reaction involves sixteen electrons; hence, it must be suprafacial on one component and antarafacial on the other. Thus, it must be a [14s + 2a] or a [14a + 2s] cycloaddition. The heptafulvene molecule is large enough that its p-electron system can twist without introducing too much strain or without losing too much p-electron overlap; hence, the cycloaddition is a [14a + 2s] process. In either case, the product has the following stereochemistry:
Structure of Aldehydes and Ketones Carbonyl carbon atom is connected to three atoms by sigma bonds. As these bonds use Sp 2 -orbitals, they found in the same plane and are 120°
Illustrate with examples: (a) Lyophilic and Lyophobic sols (b) Multimolecular and Macromolecular colloids (c) Homogeneous and Heterogeneous catalysis.
Define the both - Direct extrusion and Indirect extrusion Direct extrusion: Billet is placed in a container and forced through the die by a piston. Indirect extrusion:

What do you understand by molar conductivity at infinite dilution
Generally ionic bonds are stronger than covalent bonds. This is because in ionic bonds, electrostatic forces of attractin are involved. The positive ion (cation) and the negative
